I am trying to install latest version of six python package but I have following issues. Can\'t get rid of six 1.4.1 in mac OSX 10.10.2
sudo pip install six
Mac OS X's default python is installed as a framework.
Under the framework directory, there is an 'Extras' directory and six package is already placed there.
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.py
According to the description (https://github.com/MacPython/wiki/wiki/Which-Python), /System/Library/Frameworks/Python.framework/Versions/2.7/Extras is listed before /Library/Python/2.7/site-packages in module search path.
This means all packages already exists in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras can't upgrade.
Maybe you should install python manually and not to use default python.
