I am assuming you are here because like me, you installed a bazillion different python interpreters on mac and the whole thing is a spagetti. Today, I finally fixed my python installation. Whatever I install for python2 or python3 using pip JUST.WORKS.. My god! finally.

What the hell?

Here is what I had messed up, which you also probably did:

I had too many different python interpreters
Too many different symlinks which I lost track of
almost no package I installed with pip worked without a headache
any attempt to fix using online resources made it worse.
