Before we dive into the core topic: “How To Install Pip For Python 3.9 On Ubuntu 20.04”, it’s essential to highlight the importance of keeping your Ubuntu system updated and upgraded. Why, you may ask? Because outdated software is not only limiting in terms of new features and improvements but it’s also a security risk. Your system could become vulnerable to external threats that try to take advantage of old bugs that have been fixed in newer versions.
First and foremost, let’s update Ubuntu system package lists. The package list is essentially a database of all available applications from Ubuntu repositories.
sudo apt update
This command fetches all the new changes made to these packages and updates the Ubuntu package list accordingly, ensuring you get the latest version when downloading or upgrading software.
Now let’s discuss upgrades. An upgrade differs from an update as it not only brings your system’s existing packages up-to-date but also installs newer versions of your currently installed packages, effectively giving their functionality a boost. More importantly, these upgrades improve security with newly introduced patches and bug fixes.
Perform the upgrade via the command:
sudo apt upgrade
Beyond just ‘upgrade’, a ‘dist-upgrade’ invocation offers substantial benefits. Unlike ‘apt upgrade’, ‘apt dist-upgrade’ can remove installed packages if necessary for software upgrades. Here is how to implement such:
sudo apt dist-upgrade
At this point, your Ubuntu is now refreshed and fortified with the latest upgrades.
Next, how does all these relate to installing PIP for Python 3.9 on Ubuntu 20.04? Well, having updated your Ubuntu system ensures that you have already taken the first crucial step towards installing PIP successfully.
When dependencies or required packages are not updated properly, they can cause issues during installation. So, by performing the above steps you’ve laid the groundwork for a smooth pip3 installation, clearing the path for Python 3.9 to operate without hitches.
Installing pip for Python follows next, and it uses the just-updated-and-upgraded system:
sudo apt install python3-pip
Installation of Python package dependencies typically demands a well-planned computing environment. A scenario like installing PIP for Python 3.9 on Ubuntu 20.04 showcases this need clearly, prompting a systematic approach. I trust this helps illuminate the pre-installation updates and upgrades stage preceding pip3 installation.
For more detailed information refer on installing Python 3 on Ubuntu, DigitalOcean has a vivid tutorial.
Positively, installing Python 3.9 and Pip on Ubuntu 20.04 is undeniably a simple process. Here, my answer dives into the step-by-step guide to make your Python application development experience smoother on Ubuntu OS. The most simple, unswerving way of Python installation involves downloading it from the official site and then performing its set up on the system. However, in the case of Ubuntu, Python 3 can be installed via command-line.
To install Python 3.9, open your terminal and run the following commands:
sudo apt update sudo apt install software-properties-common
These commands ensure that your system is updated with the latest Ubuntu repositories. The next step is to add deadsnakes PPA to your sources list which comes coupled with many Python versions including Python 3.9.

sudo add-apt-repository ppa:deadsnakes/ppa sudo apt install python3.9
Once you have successfully installed Python 3.9, confirm it by typing:
python3.9 --version
Your terminal should now reflect ‘Python 3.9.X’.
After successful Python 3.9 installation, you might want to install pip, a package manager for Python that allows easy installation of modules/packages. To do this, first, ensure that your system includes curl by running the command:
sudo apt install curl
Then, install pip by grabbing its installation script from pip’s official site using curl:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Finally, execute the downloaded script for the pip installation. Ensure to specify Python 3.9 as follows:
sudo python3.9 get-pip.py
To verify if pip has been installed successfully, you can check its version:
pip3 --version
It should display like ‘pip X.XX.X from … (python 3.9)’. Your pip is linked to Python 3.9 and is ready to use.
To streamline programming in Python even further, consider making these newly installed versions of Python and Pip your default systems’ version. But always remember: test all these commands before using them on a production system. You wouldn’t want to accidentally replace or overwrite necessary components inadvertently. Furthermore, these basic steps will free you from incessant back-and-forths among outdated versions [source](https://docs.python-guide.org/starting/install3/linux/).First off, we should note that pip is a valuable tool for Python coders. It’s essentially a package manager for Python, meaning it helps programmers install the various elements they need to develop applications effectively. Now, there’s more than one way to install pip for Python 3.9 on Ubuntu 20.04, but here are two common methods:

Firstly, it’s crucial to ensure your operating system environment is up-to-date before trying to get pip going for Python 3.9. To do this, you’ll need to run the following update and upgrade commands:
sudo apt update
sudo apt upgrade
Once this is done, you can start installing Python via the terminal:
sudo apt install python3.9
When prompted, tap Y to confirm that you want to proceed.
Next, to install pip, plum in:
sudo apt install python3-pip
Similar to what you did while installing Python, affirm the installation when asked. This command installs the latest version of pip.
You’ve now installed pip using the apt package.
Method Two: Downloading from source code
The alternative method is to use the Python 3.9 source code. This involves downloading the necessary pip files and carrying out the installation manually:
Kick off by moving into the /tmp directory:
pushd /tmp
Then replicate the get-pip.py script, a Python file with all installation instructions using wget like so:
wget https://bootstrap.pypa.io/get-pip.py
Utilize get-pip.py in the next step with Python 3.9, ensuring it installs pip exclusively for Python 3.9:
sudo python3.9 get-pip.py
This will generate a bunch of outputs. Make sure to close off by confirming successful pip installation:
pip3.9 --version
Remember! Depending on the project specifications, the required library versions might differ, so consider using virtual environments.
So, those are the top techniques for getting pip installed for Python 3.9 on Ubuntu 20.04. Remember to choose the method that best aligns with your specific needs and capabilities as a coder.

python3.9 -m venv venv
source venv/bin/activate
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
This detailed breakdown of terminal operations reflected above elucidates what specific commands stick outperforms:
– The
'sudo apt update'
command updates all repositories
– The
'sudo apt install python3.9-venv python3.9-dev'
command installs both venv and dev dependencies for Python 3.9
– The
'python3.9 -m venv venv'
command creates a virtual environment using venv
– The file generated by the
'source venv/bin/activate'
command activates the virtual environment
– The
'curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py'
command fetches the get-pip script from pypa’s bootstrap page and outputs it into get-pip.py file
– The
'python get-pip.py'
command finally installs pip in your virtual environment
After executing these commands, verify that pip has been installed successfully by running the following command:
pip --version
If the installation was successful, the version of pip installed should be displayed. It’s noteworthy to point out that always keeping up-to-date with the current version of pip is greatly beneficial. If an upgrade is necessary after running your version check, simply execute the following command:
pip install --upgrade pip
Understanding the importance of pip and knowing how to install it for different Python versions like Python 3.9 on your Ubuntu 20.04 machine fortifies your capability as a professional coder. Irrespective of whether you’re managing Python packages or accessing libraries for your project, adopting pip in your toolbelt ensures smoother, more efficient operations.
For more details on Linux Terminal Commands, visit the official [Ubuntu Documentation](https://help.ubuntu.com/community/UsingTheTerminal). For learning more about pip, see the official [Pip Python Packaging User Guide](https://packaging.python.org/tutorials/installing-packages/#ensure-you-can-run-pip-from-the-command-line).The pip installation commands become a staple for Python users, especially since pip itself is a powerful tool that facilitates the installation of Python packages. Indeed, for anyone working with Python, and particularly version 3.9 on Ubuntu 20.04, understanding pip commands is essential in efficiently managing your coding environment.
To begin, let’s dissect the basic pip installation command:
sudo apt-get install python3.9 -y
This command is specifically designated to install Python 3.9 on Ubuntu operating systems. Here’s a quick breakdown of each segment:
* sudo means “Super User Do”. It allows regular users to execute commands with the security privileges of the superuser or root.
* apt-get is Ubuntu’s Advanced Packaging Tool (APT) which handles packages (applications, libraries, etc). It’s useful for automatic updates, package installation, upgrades, and more.
* install is obviously the command to instruct the system to install something.
* python3.9 is what we tell the system to install — in our case, it is Python version 3.9.
* The -y option automatically answers ‘yes’ for all prompts and runs non-interactively.
Next comes installing pip for our newly installed Python. This can be done using the following command:
sudo apt-get install -y python3-pip
When it comes to this piece of syntax, there isn’t much change:
* python3-pip simply implies that you’re seeking to install pip but for Python 3.
These two sequences lay the groundwork for your coding environment. However, with pip in your arsenal, the door opens to comfortably installing other useful packages. For instance, if one wished to add Django, they could input:
pip3 install Django
To break down this statement:
* pip3 signals that you want to use pip specifically for Python 3.
* install maintains its role as an installation command.
* Django: the name after ‘install’ will always be what you want to add to your environment.
I hope this provides insight into the syntax used when installing pip on Python 3.9 on Ubuntu 20.04. Remember, the technical wording does not need to be intimidating. It’s often about learning how different pieces fit together to perform a desired function.
For a more comprehensive guide on Linux commands, the Ubuntu Tutorial is a great resource, just as the official pip documentation. These go further into specifics, providing valuable reference material for any Python coder.Once pip is installed for Python 3.9 on Ubuntu 20.04, it’s important to verify the installation and confirm the version of pip that’s installed. This verification must be done as part of reliable post-installation steps, so it ensures that pip, a crucial package management system used to install and manage software packages written in Python, is correctly installed for the Python environment you are working with.
The following are the instructions needed to effectively verify the installed version of pip:
Given that pip should now be installed on your system, open the terminal or command-line interface on your Ubuntu machine.
We’re going to use the
pip -V
or
pip --version
command to obtain the details of the pip installation.
Your code should look something like this in the console:
$ pip3 -V
Alternatively, you could use the longer version notation:
$ pip3 --version
Both commands will yield the same result from the terminal.
In response, the terminal will show details about your pip version alongside the pertinent python version number. It might look something like this:
pip 21.0.1 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)
This indicates that pip version 21.0.1 is installed, along with its location and its association with Python 3.9.
Here are some potential issues you need to consider while analyzing the output:
– If pip isn’t installed, you’ll experience a command not found error. You would then have to revisit the pip installation process.
– If pip is installed but tied to an older version of Python, you might want to check multiple Python versions on your system.
– Lastly, if pip is installed for your intended Python version but appears outdated, consider using
pip install --upgrade pip
to upgrade Pip to its latest version.
The key takeaway here is the significance of verifying pip after installing it within Python 3.9 on Ubuntu 20.04. Reality-checking our environments provides us with the confirmation we need for smooth coding endeavors and lays an excellent foundation for future Python project setups.
As with most technical processes, the installation of pip for Python 3.9 on Ubuntu 20.04 is not always smooth and you might encounter several common pitfalls. Let’s troubleshoot some of these issues and explore possible solutions which can keep us focused on our main goal – a successfully installed package manager for our Python environment.
1. Missing Python 3.9 Development Package
When trying to install pip for Python 3.9, a common error is
configure: error: no acceptable C compiler found in $PATH
. This error message indicates that the Python development package has not been installed which would provide the necessary compilers.
To resolve this, you should install the development package with the following command:
sudo apt-get install python3.9-dev
2. Incomplete or Incorrect Python 3.9 Installation
Another pitfall could be an incomplete or incorrectly installed Python. If Python 3.9 is not properly installed, calling
python3.9
from the terminal won’t work and consequently pip installation will fail.
To fix this issue, first ensure to remove any previous python iterations for a clean install with:
sudo apt-get purge python3*
Then re-do the process of installing Python 3.9 using these commands:
sudo apt update sudo apt install python3.9
3. No Alias Set for Python 3.9
Sometimes python3.9 may have been successfully installed but not set as the default version to be used when calling
python
in your terminal. As a result, running
python --version
won’t return Python 3.9, leading to problems when trying to install pip for Python 3.9 specifically.
In order to solve this, you can set an alias for Python 3.9 using following command:
alias python=python3.9
Once these hitches are addressed, it widens up the path to successfully install pip for Python 3.9 on Ubuntu 20.04. The installation is pretty straightforward after these adjustments. All we need to do is to download get-pip.py and then run it. Here’s how:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python get-pip.py
By steering clear of the above common obstacles, one can ensure a seamless installation process for pip onto Python 3.9 on any Ubuntu 20.04 system. Remember, successful problem solving is not only about eliminating existing errors, but learning to anticipate potential ones too!

Pip is a powerful package management system used by Python developers to install and manage software packages written in Python. When you’re doing Python development, it’s often necessary to utilize different libraries that aren’t included in the standard library–that’s where pip shines[1](https://docs.python-guide.org/dev/virtualenvs/#lower-level-virtualenv). The recent Python version (as of writing) we’ll be discussing related to pip installation is 3.9.
If you’re working on Ubuntu 20.04, the relevant instructions are:
Let’s get started with a detailed step-by-step guide:
Step 1: Update Operating System Package Index
This step is crucial to ensure that the latest version of Python is installed on your system. Following inline code can be used:
sudo apt update
Step 2: Install Prerequisite Packages
Installing software-properties-common package gives us the ability to add software repositories.
sudo apt install software-properties-common
Step 3: Adding Deadsnakes PPA Repository
Deadsnakes[2](https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa) is an external package source for Python versions. Adding this repository allows you to install the latest Python versions.
sudo add-apt-repository ppa:deadsnakes/ppa
Step 4: Install Python 3.9
Once you have added the deadsnakes package, now it’s time to install Python 3.9.
sudo apt install python3.9
Step 5: Validate Installation
After installation, verify if Python 3.9 has been installed correctly.
python3.9 --version
Now, let’s move on to installing pip for our Python 3.9 version.
Step 6: Download Script to Install pip
We will be downloading get-pip.py script from the official Python Packaging User Guide website.
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Step 7: Run Script to Install pip
Finally, runget-pip.py script using Python 3.9.
python3.9 get-pip.py
Step 8: Confirm Installation
Check if pip has been successfully installed.
pip3 --version
This should return something like ‘pip 21.0.1 from /usr/local/lib/python3.9/dist-packages/pip (python 3.9)’. Exact numbers can vary, but as long as output includes ‘python 3.9’, pip has been successfully configured for Python 3.9.
Cheers! Now, through the power of pip, you can now easily install any public Python package available on PyPI, the Python Package Index, further fostering coding efficiency and productivity.Optimizing your use of Python and pip involves a deep understanding of package management and the software’s overall environment. It’s significant not only to know how to install pip for Python 3.9 on Ubuntu 20.04 but also to comprehend why you’re doing it.
Firstly, Python is an extremely versatile programming language used in various applications, from web development to data science. Pip (Pip Installs Packages) is a package manager for Python that simplifies package installation and management [Python Package Index](https://pypi.org/project/pip/).
Let’s slice through the process of installing pip for Python 3.9 on Ubuntu 20.04:
1. Update your system package list by running:
sudo apt update
2. Subsequently, install Python by entering the code:
sudo apt install python3.9
3. To get pip working for Python 3.9, you’ll have to install it separately:
sudo apt install python3-pip
Here,
sudo apt install python3-pip
installs pip targeting the python3 environment in the Ubuntu distribution.
Henceforth, after successfully installing pip for Python 3.9, there are plenty of optimizations you can make:
– Always ensure to keep your Python packages up-to-date. Regularly run
pip list --outdated
which will show you all installed packages that have newer versions available.
– Another optimization tip is to utilize Virtual Environments. This protects your main environment by providing isolated spaces for your projects, thus preventing different versions of packages from interfering with each other.
– A popular library that aids in optimizing Python usage is ‘venv’ which can be simply used as follows:
Create a new virtual environment:
python3 -m venv /path/to/new/virtual/environment
To start using this Virtual Environment:
source /path/to/new/virtual/environment/bin/activate
– Finally, handling complex dependencies and ensuring your project’s setup is reproducible is easily accomplished by using pip freeze and requirements files. You can do this by just typing into the terminal:
pip freeze > requirements.txt
This creates a ‘requirements.txt’ file, which contains a simple list of all the packages in the current environment, and their respective versions. Later on, when another developer wants to replicate the same environment, all they would need to do is:
pip install -r requirements.txt
These tips should help you optimize your use of Python and pip, so you’re not just installing packages but utilizing them efficiently to become a more proficient Python developer.
Remember, like any language or tool, proficiency comes over time and with practice. So, over time you’ll find more techniques to expedite and simplify your coding and package management process while using Python and pip. Always stay updated regarding modifications and upgrades being implemented, as these modifications are designed aimed at enhancing coding effectiveness and efficiency.
Your journey to optimization ought not to stop here. Look out for real-world problems, try to architect solutions using Python, and think about how pip can assist in maintaining the robustness and integrity of your projects. Every single problem encountered is an opportunity to learn something new and to optimize further.

[Pip Packaging User Guide](https://pip.pypa.io/en/stable/user_guide/)As you can see, installing Pip for Python 3.9 on Ubuntu 20.04 isn’t as intimidating as it might initially seem. With the right steps and patience, you can get your system equipped with Pip in no time, expanding your Python capabilities allowing you to install and manage additional packages that aren’t part of the Python Standard Library.
We broke everything down into a step-by-step process:
1) First off, we ensured our packages were up-to-date using this command:
sudo apt update && sudo apt upgrade -y
2) After that, we installed the prerequisites needed for Python before the actual installation. We used the command:
sudo apt install software-properties-common python3.9-venv python3.9-dev git-all -y
3) Next, we checked our Python version to confirm our installation with the command:
python3.9 -V
4) But to acquire Pip itself, we downloaded get-pip.py via curl and installed it. For that, these commands are used:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
and
python3.9 get-pip.py
5) Lastly, we affirmed that Pip was properly installed through checking its version via this command:
pip3.9 --version
Now, you can readily install any Python package out there with Pip. Just open the terminal, use the pip tool to install the package by typing
pip install [package name]
. That’s the beauty of having Pip installed in your system, you can easily extend the functionality of Python according to your programming needs.
Lastly, its always good practice to create virtual environments before installing new packages. This keeps your projects tidy and avoids interfering with system files or other Python projects that might have different dependencies. This is done by using these commands:
python3.9 -m venv my_env
to create a new environment and:
source my_env/bin/activate
to activate this environment. Now you can install packages locally in your project without cluttering global site-packages directory.
Just remember to deactivate the environment once finished by simply typing
deactivate
.
