Django INSTALLED_APP Resolving to "ModuleNotFoundError" - django

Question

The pip module Im using needs to be included in installed apps as such:
INSTALLED_APPS = [
...,
'django_apscheduler',
...
]
But I keep getting the following when I build my app:
ModuleNotFoundError: No module named 'django_apscheduler'
Even though the app is clearly listed in my pip list. The module in question is Django APScheduler.
EDIT: Ive already installed the module via pip install django_apscheduler, but it is listed in pip list as:
django-apscheduler # using - as opposed to _
EDIT 2: Full trace:
+ python3 manage.py test --settings=grin_app.settings.test

ModuleNotFoundError: No module named 'django_apscheduler'

Answer 1

this error happens when you have NOT installed the app.
run pip install django_apscheduler and try again.
make sure you are installing it in your python environment or in your appropriate virtual environment
