ModuleNotFoundError: No module named 'dmcaprivacy'

CodePudding user response：

You have lot of modules either not installed via pip, or not updated them via pip freeze > requirements.txt.

As such, I can identify 2 such modules:

ImportError: cannot import name 'config' from 'decouple'

Possible fix:

pip install python-decouple

2nd Error:

ModuleNotFoundError: No module named 'dmcaprivacy'

Possible fix:

Your project folder is not in correct order. Place your dmcaprivacy folder inside project folder which contains manage.py.

Then in your settings.py change:

WSGI_APPLICATION = 'dmcaprivacy.wsgi.application'

Your WSGI_APPLICATION must point to the path to your wsgi.py file.

For static files, I would recommend installing whitenoise.

Follow the steps here: http://whitenoise.evans.io/en/stable/

Finally run pip freeze > requirements.txt
