I made a website with django and I use celery for asynchronous task, when I run:
./manage.py runserver
I got the error:

ModuleNotFoundError: No module named 'kombu.transport.django'
I know that the django module was definitely removed from the kombu package but if I remove kombu I get the first error, how can I fix this ?
I am using django==3.0.3, celery==4.4.1, kombu==4.6.8
You use
celery 4.4.1 has requirement kombu<4.7,>=4.6.10, but you'll have kombu 4.6.8 which is incompatible.
Please use:
pip install celery==4.4.6
pip install kombu==4.6.10
and if you want to redis you should this version
pip install redis==3.2.1
Then you to terminal and type python

Look's like an issue with Django 1.10.x and Python 3.6:
https://bugs.python.org/issue23722
https://github.com/django/django/pull/7653/commits/5a36dbc634f4ebd7ccae8f0a4bab987b478750cb
Options are to downgrade Python to version 3.5 or to update Django to newer release.
Django errors when running via Virtual Environment: Exception in thread Django-main-thread. I am doing this in Venv and not sure where I am going wrong? Can someone please help?
Initially, I ran into this issue when I accidentally upgraded Django when PyCharm prompted it but after that, I created a Venv and moved my files over but the error seems to be persistent.

webapp_credentials.py is on .gitignore, that is why migrate can't find it.
You need this file, which is not versioned in this git repository of your link.
