Python modules for CentOS, Red Hat, or Fedora are available in their yum repositories, but they don't have as many as those hosted in Python Package Index (PyPI). PyPI modules are also generally more up-to-date.

PyPI modules can be installed using pip, but pip is not installed by default in CentOS, Red Hat, or Fedora. You can install pip using yum or dnf at the terminal.

Steps to install pip on CentOS, Red Hat or Fedora:

  1. Open terminal application.
  2. Install pip package using dnf.
    $ sudo dnf install --assumeyes python3-pip
    [sudo] password for user:

    Install python2-pip package instead if you're installing for Python 2.x.

  3. Run pip command to test if installation was successful and to check installed version.
    $ pip3 --version
    pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

    Run pip2 if you've installed python2-pip package.
