It is problem with Python 3.x.
In Python 3, distutils.LooseVersion fails to compare number and a word.
Bug already reported here. https://bugs.python.org/issue14894

If Ansible were to claim py3 support wouldn't galaxy work-a-round the issue then? Waiting on an upstream py3 fix seems to be some time away.

[retr0h]

Any update on this? Not being able to use galaxy on py36 seems like an important bug.

I've created a pull request which should address this issue in a safe way with galaxy. Due to galaxy having no guarantees on version formatting, I think the solution in that PR is the best way to go.
