如何在Mac上卸载Python

  1. Remove the Python 2.7 framework

    sudo rm -rf /Library/Frameworks/Python.framework/Versions/2.7

  2. Remove the Python 2.7 applications directory

    sudo rm -rf "/Applications/Python 2.7"

  3. Remove the symbolic links in /usr/local/bin that point to this Python version see ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/2.7' and then run the following command to remove all the links:

    1
    2
    cd /usr/local/bin/
    ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/2.7' | awk '{print $9}' | tr -d @ | xargs rm
  4. If necessary, edit your shell profile file(s) to remove adding /Library/Frameworks/Python.framework/Versions/2.7 to your PATH environment file. Depending on which shell you use, any of the following files may have been modified: ~/.bash_login, ~/.bash_profile, ~/.cshrc, ~/.profile, ~/.tcshrc, and/or ~/.zprofile.
