Migration error when calling runserver after upgrade from PSA

Got this error when trying to upgrade from python-social-auth, when running runserver:

django.db.migrations.graph.NodeNotFoundError: Migration social_django.0005_auto_20160727_2333 dependencies reference nonexistent parent node (u'social_django', u'0004_auto_20160423_0400')

As far as I can see, there is a migration social_django/migrations/0004_auto_20160423_0400.py, so not sure yet of the problem.

I am running Django 1.8.17.

If someone had used an old version (https://github.com/omab/python-social-auth) and changed it to the new version (https://github.com/python-social-auth/social-app-django), he would encounter the error.

I think this issue needs to be re-opened. I’m trying to do an upgrade and followed the migration guide and am getting the same exception:

I originally had installed and was using python-social-auth==0.2.21 and Django==1.7.11 and then installed the following:

social-auth-app-django==1.2.0
social-auth-core==1.4.0

My django_migrations looks like this:

app	name	applied
default	0001_initial	2017-01-19 14:33:43.873019+00
default	0002_add_related_name	2017-01-19 14:33:43.881544+00
default	0003_alter_email_max_length	2017-01-19 14:33:43.887557+00
default	0004_auto_20160423_0400	2017-01-19 14:33:43.893561+00
social_auth	0005_auto_20160727_2333	2017-01-19 14:33:43.899437+00

There’s possible solutions/hacks at https://github.com/omab/python-social-auth/issues/962 to get around this issue.

It seems like #4 should have fixed this, but for some reason it’s not working.
