ImportError: No module named six
You probably don't have the six Python module installed. You can find it on pypi.
To install it:
$ easy_install six
(if you have pip installed, use pip install six instead)
If pip "says" six is installed but you're still getting:
ImportError: No module named six.moves
try re-installing six (worked for me):
pip uninstall six
pip install six
On Ubuntu and Debian
apt-get install python-six
does the trick.
Use sudo apt-get install python-six if you get an error saying "permission denied".
