Installing pip on macOS Sierra

Question

I\'ve been trying to install pip on macOS sierra via brew, but every time it completes without installing the binaries in /usr/local/Cellar/python/2.7.13/bin.

For what it's worth, after upgrading to high sierra I found my machine pretty much unusable for development, even crashing plenty of times.

Regarding python, i had a rights issue inside the site-packages folder, therefore the reinstall did not work out:

$ brew reinstall python

So to fix it, I completely removed the site-packages:

$ sudo rm -rf /usr/local/lib/python2.7/site-packages

With this, reinstalling python2, and having a working pip2 again, worked like a charm:

$ brew reinstall python

$ which pip2
/usr/local/bin/pip2
$ which python2
/usr/local/bin/python2

$ which pip
pip not found
$ which python
/usr/bin/python

Hope that helps.
