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.
/usr/local/Cellar/python/2.7.13/bin
The error message has the answer for you...
Remove /Users/justin/.venvburrito/lib/python/distribute-0.6.35-py2.7.egg/ and run brew reinstall python. setuptools is the wrong version.
