Fix Mountain Lion 10.8 Python IOError pyconfig.h Error

MountainLion-Python-Fix

After upgrading to Mountain Lion : 10.8 I noticed that I was getting Python errors which prevented me from starting vim:

Traceback (most recent call last):

IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory)

First I tried the first step from this: https://gist.github.com/3180261 - which didn't stop the errors from displaying...

I still need to find where the path is being incorrectly set and fix it there, but if you need to be up and running quickly with vim, this should also work:

sudo mkdir -p /usr/include/python2.7
sudo ln -s /System/Library/Frameworks/Python.framework/Versions/Current/include/python2.7/pyconfig.h /usr/include/python2.7/pyconfig.h

Thanks for the note. I updated XCode right before upgrading to 10.8 but hadn't pulled the command line tools update yet.

This gist fixes import errors for ropemode if you are using ropevim. For some reason the embedded Python interpreter in system Vim uses a different sys.prefix from the command line version.
