Answer 1

I ran into the same problem on a new virtualenv trying to install. I'm running python 2.7.11 and found the two commands belows solve the versioning problem with setuptools:

This forces a pip upgrade, which has a fix for the bug, but doesn't reinstall setup tools, so I was still running on setuptools version 35.0.1

python -m pip install --upgrade --force pip

This sets setuptools to an older version.

pip install setuptools==33.1.1

After this, I successfully installed my requirements.
