Hmm, this is annoying. Pip itself seems to be broken, or has broken itself
in the process of updating matplotlib. I'm sorry that my advice put you
into a situation that's hard to recover from.
Can you update pip itself?
$ pip install -U pip
If you're not able to do that and pip itself is completely broken, you
should be able to recreate a working python environment from scratch by
re-running the install script:
