Answer 1

It was due to older setuptools version. I updated setuptools as follows:

sudo pip install setuptools --upgrade

It installed setuptools-31.0.0 and that worked.

Thanks. It was also due to an old pip 1.5 on my side. Don't forget to pip install -U pip ! – Andry

Answer 2

For python 3 and later 3.x, use pip3

sudo pip3 install setuptools --upgrade

No need to use sudo for a virtual environment or in admin console of windows,so use simply

pip3 install setuptools --upgrade
