The error
I get when I try to runserver
for my django app is as follows:
django.db.migrations.graph.NodeNotFoundError: Migra
It worked for me with pip install --upgrade django
I got the same error on installing a new package which also downgraded my Django to version 1.8.16
pip install --upgrade django
installed back the 1.10.3 version (on which I had been working ever since I started with my project) and that solved the problem.
