Django “Python Manage.py runserver” Error Fix!
Apr 23django 3.1 final was just released. So upgrading to the next version is always fun to test out new features.
After installing django 3.1 when you run:
python manage.py runserver
You might see this error:
Traceback (most recent call last):

ImportError: cannot import name receiver
This is because you have installed more then one version of django.
To fix this Delete django (/usr/local/lib/python2.6/dist-packages/django) Just delete the whole folder. Now reinstall django again and your working!
