How would you someone who has used pip with sudo undo the mess that has created in his computer?

Uninstall everything and start over?

Just start using virtualenv for everything. By default virtualenv starts you with a clean python setup each time and nothing you've installed globally with pip will affect you.

Yeah. You can use 'pip uninstall'.

I ended doing the following for those who are in the same situation:

    pip freeze > pip_list_with_sudo.txt
    sudo pip uninstall -r pip_list_with_sudo.txt

So now let's start doing things right with virtualenv...
