Django Rest Framework -- no module named rest_framework
Also, check for the possibility of a tiny typo:
It's rest_framework with an underscore (_) in between!
Took me a while to figure out that I was using a dash instead...
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?
