# pip3 install ansible-core
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see pypa/pip#5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

# ansible --version
-bash: ansible: command not found

[Nico Kadel-Garcia]

Why are you installing ansible as the root user? The root user typically does not have ".local/bin" in its PATH.

If your operating system has ansible-core packages, use those. RHEL 8 or later have ansible-core 2.14, with all the dependences, already bundled as a more gracefully integrated RPM.
