  Warning

  Installing Python packages with pip as the root user places files in system locations. This can override RHEL libraries and might cause system instability or conflicts with supported packages. Red Hat does not support software installed by using pip at the system level. To avoid these issues, use pip within a virtual environment or install packages as a non-root user with the --user option.

Procedure

• To run the Python 3.9 interpreter or related commands, use, for example:

  $ python3
  $ python3 -m venv --help
  $ python3 -m pip install package
  $ pip3 install package

  $ python3.11 -m venv --help
  $ python3.11 -m pip install package
  $ pip3.11 install package
