Importing django reversion gives an error

Question

I have the need to add version control for my models in the django admin and for that reason I have installed django-reversion from here.My server does not have have internet connectivity so I could not use pip.I had to manually download the zip file from github,upload it on to my server,extract the contents and run python setup.py install to install reversion.

However,when I try to import it,I get the following error :

root@ns1 /home/project# python

>>> import django

>>> import reversion

As per the github page,the current reversion version is 1.8.0 and should be compatible with django 1.6. What could be the problem ?

I know this is an old question, but in case anyone stumbles upon it: The problem here is that you're running the standard python interpreter, rather than the Django shell. You can do import django into a regular python interpreter to check the Django version, but it does NOT set all the various environment variables necessary to run django properly -- including importing django apps. In order to import a django app, you need to instead run the Django shell via

./ python manage.py shell
