how to uninstall pyenv(installed by homebrew) on Mac

From the docs:

Uninstalling pyenv

The simplicity of pyenv makes it easy to temporarily disable it, oruninstall from the system.

1. To disable Pyenv managing your Python versions, simply remove the pyenv init line from your shell startup configuration. This will remove Pyenv shims directory from PATH, and future invocations like python will execute the system Python version, as before Pyenv.

   pyenv will still be accessible on the command line, but yourPython apps won't be affected by version switching.

2. To completely uninstall pyenv, perform step (1) and then remove its root directory. This will delete all Python versions that were installed under $(pyenv root)/versions/ directory:

   rm -rf $(pyenv root)

   If you've installed Pyenv using a package manager, as a final step perform the Pyenv package removal. For instance, for Homebrew:

    brew uninstall pyenv

None work for me (under brew) under Mac Cataline.

They have a warning about file missing under .pyenv.

(After I removed the bash_profile lines and also rm -rf ~/.pyenv,

I just install Mac OS version of python under python.org and seems ok.

Seems get my IDLE work and ...

Try removing it using the following command:

brew remove pyenv
