PIP is a Python package manager allowing you to install and manage packages not part of the Python standard library. All Python packages are hosted on an online repository called Python Package Index. PIP connects this repository, then downloads and installs Python packages to your system. PIP provides a simple and easiest way to install locally user-defined projects using a setup.py file. PIP is a command line utility that helps you to install, reinstall, or uninstall packages with a single command.

This post will show you how to install and manage Python packages using PIP on Fedora.

Install PIP on Fedora

By default, the PIP package is not installed on Fedora, so you will need to install it first. You can install it using the following command.

dnf install python3-pip

Once the PIP package is installed, you can verify the PIP version with the following command.

pip3 --version

Output.

pip 21.0.1 from /usr/lib/python3.9/site-packages/pip (python 3.9)

It is also recommended to upgrade PIP to the latest version. You can upgrade it with the following command.

pip3 install --upgrade pip

Output.

Requirement already satisfied: pip in /usr/lib/python3.9/site-packages (21.0.1)
Collecting pip
  Downloading pip-23.1.2-py3-none-any.whl (2.1 MB)
     |████████████████████████████████| 2.1 MB 12.6 MB/s 
Installing collected packages: pip
Successfully installed pip-23.1.2

Now, verify the PIP version again with the following command.

pip3 --version

Output:

pip 23.1.2 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)

To see all available options of the PIP command, run the following command.

pip3 --help

Output.
