Django runserver error after startproject - django

Question

I'm new to Django and web frameworks in general. Right off the bat, I can't seem to run the server after django-admin startproject mytestsite. I've tried this with and without a virtual environment, and with Python's built-in virtual environment tool as well as virtualenv.
This is the error I get:
(my_django_environment) MacBook-Pro:mytestsite alialsabbah1$ python3 manage.py runserver
Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x108caef28>

I'm not really sure where to even start with this.
