Объект типа ContentType не имеет атрибута objects

Я использую djangae с некоторыми сторонними приложениями, такими как all-auth, django-invitations и django rest framework. Когда я нажимаю python manage.py migrate, я получаю следующую ошибку.

AttributeError: type object 'ContentType' has no attribute 'objects'
