Installation error

Hi,

I'm trying to install Calvin on Ubuntu 12.04 with "python setup.py install" and I receive this error message:

"apt-get install python-mock" seemed to help

You beat me to it.

python setup.py install does not automatically resolve dependencies, so you need to handle them yourself. One way of doing it is to use pip for installation, e.g.

pip -r requirements.txt -r test-requirements.txt -e .

We're working on improving the setup process. Hopefully, it should become a bit easier in the next release.

Cheers,
