You are using pip version 8.1.2, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Hi @perfecto25,

This appears to be an issue with your version of setup tools as described here in this other bug: pypa/pip#4104

Please update setuptools and get back to me on whether that works or not.

If that doesn't work, try updating pip as suggested by pip itself on the excerpt you provided:

pip install --upgrade pip

If still that doesn't work, please let me know what is your operating system and which version and I will try to simulate the issue to go back and try to fix it.

Thank you!
