Noteworthy is the fact that even though Python development has ceased for version 2.7, it still holds immeasurable applications due to which this guide abides in relevance. For comprehensive information, refer to Python2.7 official documentation.

Given a scenario where you want to perform a soft installation without modifying system files, there’s an option to use virtual environments (

virtualenv

). A virtual environment helps you isolate the Python and Pip versions from system-wide installed versions. To create one, follow these steps:

– Make sure you have installed the `virtualenv` package. If not, run: 

sudo apt install virtualenv

– Create a new Python 2.7 virtual environment: 

virtualenv -p /usr/bin/python2.7 venv

– Activate the environment: 

source venv/bin/activate

Once activated, any packages you install using pip are installed into this isolated environment, preventing potential conflicts with system-wide packages.

Pip plays a vital role in our efforts to master Python. It empowers us to incorporate a colossal number of third-party libraries that Python developers have made available—further equipping the powerful language of Python!

Ubuntu 20.04, known as Focal Fossa, represents a significant departure from previous versions of Ubuntu in several ways. Most notably for Python developers, Ubuntu 20.04 has officially phased out support for Python 2.7 and now features Python 3.8 as the default version.

This move aligns with the larger trend in the Python community to transition away from Python 2.x after it reached its date of End-Of-Life (EOL) on January 1, 2020 (Python 2 EOL countdown).

The deprecation of Python 2.7 likewise impacts associated packages and tools, such as pip—the package installer for Python—which no longer supports Python 2.7 in versions post pip 21. Barring a few workarounds, these changes represent a series of challenges that developers will have to navigate when working with legacy Python codebases on Ubuntu 20.04.

To install pip for Python2.7 on Ubuntu 20.04 despite the challenges represented by defaulting to Python 3.8, you can perform the following steps:

  1. First, download the version of python that you want. You can do so using the wget command with your chosen version urls taken from Python Release Page. For example,

    wget https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz

  2. Then extract and go inside the downloaded file directory. This guide uses tar to extract:

    tar xzf Python-2.7.18.tgz
cd Python-2.7.18

  3. Before building Python, ensure that the necessary set of build dependencies are installed on your machine:

    sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev 
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm 
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev

  4. Now you can configure and make build to prepare for installation:

    ./configure --enable-optimizations
make

  5. Once built successfully, you can now install this version of Python:

    sudo make altinstall

  6. About Pip, As pip has dropped support for Python 2.7 since version 21, we must install an older version through the get-pip.py script:

    curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
sudo python2 get-pip.py

Now, you have Python 2.7 and pip installed side by side with the existing version of Python 3.8 (the system’s Python) in Ubuntu 20.04 LTS which allows for working on projects that still rely on the deprecated version of Python.

Depending on your development needs, you may want to use virtual environments (venv or virtualenv) to isolate your Python 2.7 environment and further manage its packages.

Benefits of this method:
All commands are terminal based, minimizing system overhead and maximizing compatibility and control.
By manually downloading, extracting, and installing Python and pip, you know exactly where everything is installed, which can be helpful for troubleshooting purposes.
You can maintain the newer Python 3.8 on your system for all system related functionalities and other projects.
You can operate multiple versions of python independently, which helps avoid potential conflicts between different project requirements.

However, a little caution here, continuously patching old versions could lead to security vulnerabilities. It is recommended to eventually align your projects with the current active versions of language/tools for more long term stability.

It’s important to note that Python 2.7 is no longer officially supported as of January 1st, 2020 (Python). You might face some difficulties in getting updates and resolving dependencies for pip on Python 2.7, especially on a newer OS version like Ubuntu 20.04 which has migrated mostly towards Python 3 compliance.

However, it’s completely plausible that you could be working on a legacy project or constraints that still need Python 2.7, so let’s talk about how you can install pip for Python 2.7 on Ubuntu 20.04, along with the pros and cons of doing so.

How to Install Pip for Python2.7 on Ubuntu 20.04

The following are the commands used for installing ‘pip’ for Python 2.7 in Ubuntu 20.04:

sudo apt update
sudo apt install python2
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
sudo python2 get-pip.py

The above commands first update your package list and then install Python 2. After downloading the pip installer suitable for Python 2.7 using the curl command, we execute this downloaded python file using the Python2 interpreter to install pip.

Pros of Installing Pip for Python2.7:

  • Legacy code support: If your project is built on Python2.7, being able to use pip just makes dependency management smoother.
  • Learning and debugging older projects: Understanding and debugging legacy code requires the same development environment as was used initially. Hence, having pip installed for Python2.7 comes handy here.

Cons of Installing Pip for Python2.7:

  • No official updates: Since Python 2.7 is no longer officially supported, you won’t receive security updates and bug fixes from the official Python community for this version.
  • Dependency issues: With most new libraries and Python packages focusing on Python 3, you might have dependency conflicts between packages created for different Python versions.
  • Security concerns: Using an unsupported language version can lead to potential known security vulnerabilities that have been patched in newer versions but left unattended in Python 2.7.

In summary, while there may be valid reasons to continue using Python 2.7 and thus require pip installation for it, always balance it against the risks involved with sticking to outdated software versions. Remember the overall maintenance effort in terms of learning, updating, and migrating to newer languages often outweighs resistance to change due to familiarity or comfort.Before you embark on the installation process of pip for Python2.7 in Ubuntu 20.04, there are several pivotal prerequisites that need to be in place. These steps are crucial as they prepare your system for the successful installation of Pip – the package manager for Python that allows you to install and manage additional packages that are not part of Python’s Standard Library.

Pivotal Prerequisites:

  1. Existing Python Installation:

    Pip is a Python package manager and therefore requires a Python installation. Despite Python3.x being the default Python version in recent Linux distributions like Ubuntu 20.04, Python2.7 can still be installed and used in tandem. Below is the command to confirm if Python 2.7 is installed on your Ubuntu 20.04:

    python --version

    If it is installed, this command should return ‘Python 2.7.x’. If Python2.7 is not installed, you can easily get it through the following command:

    sudo apt-get install python-minimal
  2. Updated System Packages:

    To ensure your entire system is updated before installing new packages, execute this:

    sudo apt-get update 
sudo apt-get upgrade
  3. Internet Connection:

    An active Internet connection is needed in order to download Pip and possibly other dependent packages from the internet.

After these prerequisites are established, we can now proceed to the actual installation of Pip for Python2.7.

Installing Pip for Python2.7:

Now that Python 2.7 and your Ubuntu 20.04 system are ready, you can proceed to install Pip by typing into the terminal:

sudo apt-get install python-pip

This command will trigger Ubuntu to fetch Pip from its repositories and begin the installation process. Once completed, you will have Pip installed on your Ubuntu 20.04, specific for Python2.7.

After the installation, verify whether pip was successfully installed by issuing the command:

pip --version

It should output a version number indicating that Pip is indeed installed, along with some additional information about the location of the binary and the associated Python version. For example:

pip 9.0.1 from /usr/lib/python2.7/site-packages (python 2.7)

If you see something similar, congratulations! Pip has been successfully installed, and you’re ready to start adding Python packages using pip install. As a professional coder, knowing Python and how to use Pip will undoubtedly open up an expansive world of opportunities when it comes to software development.sourceOf course, if you’re using Python 2.7 on Ubuntu 20.04 and need to install pip, follow the outlined steps:

Step 1: Check for Python 2.7

First, confirm that Python 2.7 is installed in your machine. It’s always good practice to check for the version of python you plan to use before installing any packages.

Open your terminal application and type:

$ python2.7 -V

This should display something like “Python 2.7.18”. If Python 2.7 isn’t present, then install it with:

$ sudo apt install python2.7

Step 2: Get the script for Pip installation

Next, we’re going to download a Python script from the official pip repository which allows us to install pip.

From your terminal paste this code snippet:

$ curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py

The cURL command is used here to download the ‘get-pip.py’ file via the specified URL. The ‘–output’ flag writes the output to a file called ‘get-pip.py’.

Step 3: Run the Pip install Script

Now that we have the script, let’s run it to install pip. To execute the script you downloaded, use:

$ sudo python2.7 get-pip.py

Running the script should start the installation process. Remember to use `sudo` to grant necessary permissions.

Step 4: Confirm the Pip Installation

After successful installation, verify your installation by checking the pip version:

$ pip2.7 --version

This will display the pip version installed, hence confirming if your installation was successful.

There you go! Now, you should have pip installed for Python 2.7. You can begin proceeding with whatever Python 2.7 projects require pip.

Remember, considering the fact that Python 2.7 has approached its end of life, it’s advisable to upgrade to the newer versions of Python, they are generally more robust and come equipped with better features.

Also, keep in mind these commands should be executed sequentially. Make sure to run them one at a time to catch any errors or issues that may occur and rectify them immediately before moving forward.

For more information on how to use pip, you may read the pip documentation available in the official Pip User Guide.

If you’ve ever worked with Python, you are probably familiar with its package manager, Pip. Pip is essential for installing and managing Python packages. However, in Ubuntu 20.04, the default version of Python is 3.8.x while some legacy projects might still need Python 2.7 to run

Pip isn’t pre-installed on Ubuntu 20.04. You’ll need terminal commands to get it onto your system, pointing out the crucial role they play during installation processes.

The good news is, you can accomplish this using the command line interface (CLI). Terminal commands are central to this process because they allow us direct interaction with the operating system. CLI often provides more powerful functionalities compared to graphical user interface applications. Remember that every command executed will have an effect on your system, so it’s beneficial to understand what each one does.

Here’s how you use terminal commands to install pip for Python 2.7 in Ubuntu 20.04:

You should first update the package list for the software you’re currently using. More precisely, type the following code into the terminal.

sudo apt-get update

This command refreshes your local package index. It doesn’t upgrade your software but ensures that your Ubuntu system knows about the newest versions available.

Next, you must check if Python 2.7 is already installed using the command:

python2.7 --version

If it’s not installed, it can be done through the following command:

sudo apt-get install python2.7

After successfully installing Python 2.7, you can then get Pip. Start by downloading the installation script from Pypa.io. Via the command:

wget https://bootstrap.pypa.io/get-pip.py

This command retrieves the get-pip.py script. The ‘wget’ utility is a free networking tool that retrieves content from web servers. It makes HTTP, HTTPS, and FTP requests to download files from the internet.

Finally, use Python 2.7 to run the downloaded Pip installation script, like so:

sudo python2.7 get-pip.py

The ‘sudo’ before the python interpreter makes sure that the script gets the permissions it needs to install Pip system-wide. However, remember that you may need to enter your account password to use ‘sudo’. After getting through these steps, you should have Pip installed!

To verify whether Pip was successfully installed for Python 2.7, you can print the Pip version information:

pip --version

In the output, make sure that the printed version number starts with ’20’ and that the location of the binary includes python2.7.

As seen in the process above, all actions related to installing Pip for Python2.7 on Ubuntu 20.04 are performed entirely using terminal commands—reinforcing their importance and effectiveness in managing Linux systems.

Both the Apt package tool and Manual downloading represent methods for installing software onto your Ubuntu 20.04 system. Comparing these techniques in the context of installing Pip for Python2.7 reveals their distinct mechanisms, uses, advantages, and potential drawbacks.

The Apt Package Tool

The Advanced Packaging Tool (Apt) is a command-line utility that serves as your gateway to software management in Ubuntu. It provides high-level package handling operations and simplifies the process of managing software on Unix/Linux systems.

sudo apt update
sudo apt install python2.7
sudo apt install python-pip

With this installation method, it’s remarkably easy to install Pip for Python 2.7 on Ubuntu 20.04. However, keep in mind that from Ubuntu 20.04 onwards, the python-pip package has dropped support for Python2 [source] which leaves manual method as the only feasible choice.

Manual Installation Method

On the other hand, installing Pip by manually downloading enables you to obtain a specific version of the software directly from the source. This method requires attention to keeping packages updated since unlike Apt, it doesn’t auto-upgrade installed modules.

cd /usr/lib/python2.7
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
sudo python2.7 get-pip.py

With the manual download method, you can ensure compatibility with Python2.7 by specifically acquiring the latest Pip version that supports it.

Drawbacks

While both methods are viable, they have various drawbacks. The Apt package tool offers simplicity but lacks flexibility – you cannot choose specific versions nor have direct control over where packages are installed. Conversely, the manual installation method gives you full control over software versions and location, but it requires more work when it comes to updates and maintenance, making it potentially less secure.

Analyzing these methods from an SEO perspective:

• ‘Apt package tool’ and ‘manual download’ are searched around 100-1k times monthly on global scale[source].
• Python2.7 and Ubuntu 20.04 are well-recognized terms in the developer community and their combination gives an organic touch to the content.
• ‘Install Pip for Python2.7 in Ubuntu 20.04’ is a long-tail keyword serving search intent.

In conclusion, while the Apt package tool is faster and handy when installing pip on Ubuntu, the particular use-case of installing pip for Python2.7 on Ubuntu 20.04 becomes more achievable using the manual download method as it allows specific version control. Both techniques have their own relevance and usability, adding flexibility in software installation. Your optimal choice will depend on the requirements of your specific situation.

pip

is an essential tool for Python programming, enabling the installation and management of Python packages. As of Ubuntu 20.04, Python 3.x is the default interpreter. But if you’re still working with Python 2.7, installing pip for it might be a bit trickier.

1. First Method: Get-Pip.py Installation Script

One of the common ways to install 

pip

to your Python2.7 interpreter would be through the 

get-pip.py

installation script. This approach allows you to target the specific Python interpreter that you would like to use.

Here’s how you can do this:

– First, download 

get-pip.py:

bash
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py –output get-pip.py

– Then, execute the downloaded script with your desired Python interpreter (in our case Python 2.7):

bash
python2.7 get-pip.py

The get-pip.py script installs pip into the Python interpreter that executes it. So here, it’ll install pip suited for Python2.7.

2. Second Method: OS Package Manager

Another method is to use the package manager provided by your operating system. For Ubuntu 20.04, you can use 

apt:

bash
sudo apt install python-pip

Note that, since Python2.7 is not the default in Ubuntu 20.04, this may not work as expected. Typically, the packaged version of pip links to the system’s default Python interpreter.

3. Third Method: Use virtualenv

A third way to manage Python dependencies, including pip, is virtualenv. A virtual environment isolates your Python setup on a per-project basis. This lets you have different versions of the same packages (or even Python itself) co-exist without any conflict.

Install it using:

bash
sudo apt-get install python-virtualenv

Then create a new environment targeting Python 2.7:

bash
virtualenv –python=/usr/bin/python2.7 myenv

Activate the environment:

bash
source myenv/bin/activate

In your active virtualenv, pip will automatically associate with the correct Python version.

These methods place pip at your disposal, facilitating seamless package installation and management for your Python2.7 projects in Ubuntu 20.04. Whether you’re partial to the more straightforward get-pip.py approach or drawn to the more versatile virtualenv route, one thing remains certain: mastering pip profoundly enhances your Python programming experience.While installing Pip for Python2.7 in Ubuntu 20.04, you can come across a number of pitfalls. From compatibility issues to missing dependencies, the process may not always be as straightforward as you’d like. However, with some time-tested troubleshooting strategies, these pitfalls can be overcome easily.

Kernel Compatibility Issues

See also

The first common issue coders encounter while installing Pip for Python2.7 on Ubuntu 20.04 is kernel compatibility. A mismatch between your kernel version and the python version can cause installation failures.

To address this potential issue, it’s critical first to ensure that your system satisfies the prerequisites for Python2.7. Use the following command:

sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev

These commands will automatically install all the required libraries and dependencies for Python2.7. In the absence of these, the installation process could fail or linger.

Package Not Found Issues

Another common pitfall during Pip installation for Python2.7 comes in the form of ‘Package Not Found’ Errors. As at the update of Ubuntu 20.04, the Universe repository doesn’t include Python2.

To get past this hurdle, we need to download the Python2.7 installation package manually from source:

Go to Python download page, find the appropriate package and use the following command to download the file:

wget

Subsequently, extract the file using below commands:

tar -xf Python-2.7.18.tgz
cd Python-2.7.18

Next up, build Python2.7 from source using these commands:

./configure --enable-optimizations
make -j8
sudo make altinstall

If everything went well, verify the Python version:

python2.7 -V

Installing an Old Version of Pip

Having installed Python2.7, the next step is installing Pip. Bear in mind, Pip stopped supporting Python2 at version 21.0. This makes the generic “pip install” instructions inappropriate here.

Navigate to: Pip installation guide and follow the outlined instructions. It’s advisable you go for Pip version 19.2.3 as it is compatible with Python2.7.

You’ll have to use 

wget

command to download older versions of Pip:

wget https://bootstrap.pypa.io/pip/2.7/get-pip.py

Then use 

python2.7

to run the script:

python2.7 get-pip.py

You should now have both Python2.7 and Pip installed on your Ubuntu 20.04 machine without any significant hurdles. With the right versions matched and the optimal setup, this process could be smooth sailing despite common pitfalls associated with it. Stay cautious of the indicated pitfalls within this discussion and you’ll be just fine!

When you’re trying to install pip for Python2.7 on Ubuntu 20.04 and encountering errors, it can be discouraging. But don’t worry, I’m going to guide you through the process of untangling those error messages and getting pip installed successfully.

Firstly, we need to understand that Ubuntu 20.04 comes with Python3 packaged and no longer supports Python2 by default. This implies that installing pip for Python2.7 in Ubuntu 20.04 might throw some errors. Let’s break down a possible solution for you to follow:

* Check whether Python2 is already installed. If not, install it using these commands:

sudo apt update
sudo apt install python2

Here, 

sudo apt update

updates your package list while, 

sudo apt install python2

installs Python2.

* Next, download get-pip.py script from its official source. You can use curl command as follows:

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py

This command fetches the get-pip.py script which we will run to install pip. We specify the –output flag to write the output into a file named get-pip.py.

* Run the downloaded script with Python2:

python2 get-pip.py

Here, 

python2 get-pip.py

tells your system to execute the get-pip.py script using Python2.

Now, if you’re riddled with errors here are few common ones and their solutions:

1. Package ‘python-pip’ has no installation candidate: This happens because the package has been removed or isn’t available with the current sources. It may have been phased out. This problem can be solved using the above steps.

2. Could not fetch URL There was a problem while connecting to pypi.python.org: This indicates a network connection error. You may want to check your internet connectivity or firewall settings, making sure port 443 (https) is open for outgoing connections.

Normally, following the aforementioned steps should help you solve any issues related to installing pip for Python2.7 in Ubuntu 20.04. However, if you’re still having trouble, try searching your error messages online, chances are someone’s faced them before and found a solution.

I hope this cleared up your confusion! Remember, error messages aren’t there to obstruct you but aids in understanding what’s gone wrong and how to resolve it. Happy Coding!

Do remember Python2.7 is deprecated as of January 1st, 2020 (source). While you may have certain legacy tools or scripts requiring Python2, always ensure to migrate to Python 3 whenever you can to benefit from continuous security, features, and improvements updates provided by Python maintainers.

Maintenance Tips: Upgrading & Uninstalling the Installed Packages Using PIP
