I suspect the clue is right there in the error message.

The model is probably being imported into a script being executed early, but django.contrib.contenttypes is either missing from INSTALLED_APPS or the contenttypes app is not yet "ready". If it is there, make sure the punctuation around it is valid (commas etc). It may also be related to the order of apps in the INSTALLED_APPS array althought I am not sure if that is an issue with contemporary Django anymore.
