Answer 1

None of the other uninstall/reinstall/force answers worked for me, but on OS X 10.10.5 with the system Python 2.7.10, I was able to do:

pip uninstall packaging pip
easy_install pip # this installed pip 1.4.1
pip install --upgrade pip # and this upgraded to the current pip

and I was then able to import pkg_resources without a problem.

Should really learn to stop messing with the system Python…
