Unable to upgrade python six package in mac osx 10.10.2

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 --upgrade
Requirement already up-to-date: six in /Library/Python/2.7/site-packages
Cleaning up...

pip search six
six - Python 2 and 3 compatibility utilities
INSTALLED: 1.9.0 (latest)

python -c "import six; print six.version"
1.4.1

which -a python
/usr/bin/python
which -a pip
/usr/local/bin/pip

What is wrong here? Can't upgrade six!

Solution

  • 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.
