Description

If the file models.py is empty in your app directory, migrations fail with LookupError. If you delete the file, the error disappears.

What I Did

python manage.py startapp newapp

Leave models.py empty and add 'newapp' to your INSTALLED_APPS.

python manage.py migrate

LookupError: No installed app with label 'newapp'.
