How to uninstall Python 2.7 on a Mac OS X 10.6.4?

Posted by: admin November 1, 2017 Leave a comment

Questions:

I want to completely remove Python 2.7 from my Mac OS X 10.6.4. I managed to remove the entry from the PATH variable by reverting my .bash_profile. But I also want to remove all directories, files, symlinks, and entries that got installed by the Python 2.7 install package. I’ve got the install package from http://www.python.org/. What directories/files/configuration file entries do I need to remove? Is there a list somewhere?

Answers:

The complete list is documented here. Basically, all you need to do is the following:

  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:

    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.

This one works:

cd /usr/local/bin/
ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/2.7' | awk '{print $9}' | tr -d @ | xargs rm

Description:
It list all the links, removes @ character and then removes them.

If you installed it using the PKG installer, you can do:

pkgutil --pkgs

or better:

pkgutil --pkgs | grep org.python.Python

which will output something like:

org.python.Python.PythonApplications-2.7
org.python.Python.PythonDocumentation-2.7
org.python.Python.PythonFramework-2.7
org.python.Python.PythonProfileChanges-2.7
org.python.Python.PythonUnixTools-2.7

you can now select which packages you will unlink (remove).

This is the unlink documentation:

 --unlink package-id
             Unlinks (removes) each file referenced by package-id. WARNING: This command makes no attempt to perform reference counting or dependency analy-
             sis. It can easily remove files required by your system. It may include unexpected files due to package tainting. Use the --files command first
             to double check.

In my example you will type

pkgutil --unlink org.python.Python.PythonApplications-2.7
pkgutil --unlink org.python.Python.PythonDocumentation-2.7
pkgutil --unlink org.python.Python.PythonFramework-2.7
pkgutil --unlink org.python.Python.PythonProfileChanges-2.7
pkgutil --unlink org.python.Python.PythonUnixTools-2.7

or in one single line:

pkgutil --pkgs | grep org.python.Python | xargs -L1 pkgutil -f --unlink

Important: –unlink is not available anymore starting with Lion (as of Q1`2014 that would include Lion, Mountain Lion, and Mavericks). If anyone that comes to this instructions try to use it with lion, should try instead to adapt it with what this post is saying: https://wincent.com/wiki/Uninstalling_packages_(.pkg_files)_on_Mac_OS_X

Uninstalling with brew uninstall python will not remove the natively installed python but rather the verson installed with brew.

In regards to deleting the symbolic links, I found this to be useful.

find /usr/local/bin -lname '../../../Library/Frameworks/Python.framework/Versions/2.7/*' -delete

I uninstalled Python 2.7.10 on Mac OSX Yosemite by doing the following “brew uninstall python”. It successfully completed as follows:

John-Mulhall-MacBook-Pro:~ js$ brew uninstall python
Uninstalling /usr/local/Cellar/python/2.7.10... (4777 files, 78M)
John-Mulhall-MacBook-Pro:~ js$ 

Obviously you have to have brew installed first for this to work…

**If you want to uninstall the Python3 with brew:

brew uninstall --force python3

No need to uninstall old python versions.

Just install new version say python-3.3.2-macosx10.6.dmg
and change the soft link of python to newly installed python3.3

Check the path of default python and python3.3 with following commands

“which python” and “which python3.3”

then delete existing soft link of python and point it to python3.3

Onur Güzel provides the solution in his blog post, “Uninstall Python Package from OS X.

You should type the following commands into the terminal:

  1. sudo rm -rf /Library/Frameworks/Python.framework
  2. cd /usr/local/bin
  3. ls -l . | grep '../Library/Frameworks/Python.framework' | awk '{print $9}' | xargs sudo rm
  4. sudo rm -rf "/Applications/Python x.y"

    where command x.y is the version of Python installed. According to your question, it should be 2.7.

In Onur’s words:

WARNING: This commands will remove all Python versions installed with packages. Python provided from the system will not be affected.

If you have more than 1 Python version installed from python.org, then run the fourth command again, changing “x.y” for each version of Python that is to be uninstalled.
