How to Install pip for Python3 on Ubuntu 22.04

7K

A package manager called Pip is used to install, upgrade, configure, and manage Python dependencies. Using pip, you can search for, download, and install packages from the Python Package Index (PyPI) and other package indexes.

This page has instructions on how to set up pip on Ubuntu 20.04 to 22.04 for both Python 3 and Python 2. Along with that, we will show you how to use pip to install and manage packages.

How to install pip for Python 3

In Ubuntu versions 20.04 through 22.04, installing pip for Python 3 is a breeze. Execute the following in the terminal as the root or sudo user:

sudo apt update
sudo apt install python3-pip

All the prerequisites for constructing Python modules are also set up using the preceding command.

When everything is set up, double check by looking at the pip version:

pip --version

The version number may vary, but it will look something like this:

pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

How to install pip for Python 2

The Ubuntu 22.04 repositories do not have Pip for Python 2. We’ll use the get-pip.py script to set up pip for Python 2.

If Python 2 is not already on your system, you can install it by running:

sudo apt update
sudo apt install python2

To get the get-pip.py script, use curl:

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

To install pip for Python 2, run the script as the sudo user with the python2 binary:

sudo python2 get-pip.py

Using the above command installs pip everywhere. If you only want it installed for your user, run the command without sudo. The script also installs the setuptools and wheel packages, which let you set up source distributions.

Print the pip version number to verify the installation:

pip2 –V
pip 20.3.4 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)

How to Use Pip

The following part will teach you the fundamental pip commands you’ll need. Enter the following to see a complete list of pip commands and options:

pip --help

Using pip command> —help, you can learn more about that command. If you want to know more about the install command, for instance, you may type:

Pip install --help

How to install Packages with Pip

The most fundamental use for the pip tool is to do an installation. Suppose you’re interested in setting up NumPy.

This is the command to perform if you want to install a package’s most recent version:

pip install <package_name>

You may type to set up the NumPy package.

pip install numpy

After the package name, append == and the version number to install a specific revision:

pip install numpy==1.18.5

Replace pip with pip2 if using Python 2.

How to install Packages with Pip using the Requirements Files

A Python project’s requirement.txt file specifies the pip packages and their versions that are needed to compile and operate the project.

The following command will install the contents of a file containing a list of prerequisites:

pip install -r requirements.txt

Listing Installed Packages

Use the “list” pip subcommand to see a list of all currently installed packages:

pip list

Upgrade a Package With Pip

To update an existing installation to the most recent version, type:

pip install --upgrade package_name

Uninstalling Packages With Pip

This is the command you need to execute in order to remove a package:

pip uninstall package_name
