TOX testing on PythonAnywhere

I'm trying to set up and run tox on PythonAnywhere.

Any tips / tricks on getting tox installed and set up? Obviously I can't do easy_install since I don't have write permissions to /usr/local/lib/python2.7/site-packages/. I could use virtualenv, but how would tox then get access to the multiple versions of python installed on the system?

Thanks :)

have you tried:

pip install --user tox
