django 1.11 with celery 4.0 and djcelery compatibility issues - django

Question

I currently use django 1.11 and I'm forced to use an older version of celery (3.1) for compatibility reasons.
I want to upgrade to celery 4.0 because another part of our application needs the later version of celery.
Is there a combination of celery, django-celery and django 1.11 that is compatible? The docs say that celery 4.0 is compatible with all versions of django from 1.8 onwards, but this does not seem to be the case.
Errors occur for example when I use:
python manage.py makemigrations <appname>
Here is the error message I get:
Traceback (most recent call last):

from celery.utils.timeutils import maybe_timedelta
ImportError: No module named timeutils
If I revert back to celery 3.1, it works.

You are using django-celery, a library which is no longer required since celery 3.1
Previous versions of Celery required a separate library to work with
Django, but since 3.1 this is no longer the case. Django is supported
out of the box now ...
Remove djcelery from INSTALLED_APPS, follow the linked document to see if anything else needs an update and it should work.
