pip install fails

Hello,

pip install ovh fails on:

from six.moves import UserString
ImportError: cannot import name 'UserString'

However six is available:

Python 3.5.1 (default, Mar  3 2016, 09:29:07)
[GCC 5.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from six.moves import UserString

$ uname -a Linux xxxx 4.5.3-1-ARCH #1 SMP PREEMPT Sat May 7 20:43:57 CEST 2016 x86_64 GNU/Linux

You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

This is definitively strange. Have you tried installing ovh in a fresh virtualenv? It is not generally recommended in Python to mix user installed packages with system managed ones.

Thanks. I tried on another machine (still on Arch) and I did not get the problem:

It looks like there is some interference with the sphinx package.

However I'll check again with virtualenv tomorrow.

Good to know! Let me know if you see something we can improve after your tests.

It is OK with virtualenv. Thanks
