Django Rest Framework -- no module named rest_framework
If you're using some sort of virtual environment do this!

Exit from your virtual environment.
Activate your virtual environment.

After you've done this you can try running your command again and this time it probably won't have any ImportErrors.
I've installed django rest framework using pip install djangorestframework yet I still get this error when I run "python3 manage.py sycndb":

ImportError: No module named 'rest_framework'

I'm using python3, is this my issue?
