Yeah It's my fault. The error occurred because I use python-decouple for fetching the environment variables from the .env file which is ignored in the git repository. Python Decouple is very useful tool for hiding the SECRET_KEY of Django which is very recommended when your deploy Django to production.

Solution:
The simplest solution for your issue is to edit the chatsite/settings.py file and clear out the import statement for python-decouple by removing from decouple import config and also using any random value for SECRET_KEY by changing SECRET_KEY = config("PROJECT_KEY") to SECRET_KEY = 'abc'.

Make the following changes in chatsite/settings.py file and run the Django server again by python manage.py runserver.

If you want to know about the use of python-decouple then just reply me.

Hey Alex,

I have cloned one project not yours but other from github and had this same error:
from .base import *
File "H:\study material\Web development\React\ecom\django-ecommerce\djecommerce\settings\base.py", line 2, in
from decouple import config
ModuleNotFoundError: No module named 'decouple'

I tried solution the way you mentioned above like this :
import os

BASE_DIR = os.path.dirname(os.path.dirname(
os.path.dirname(os.path.abspath(file))))
SECRET_KEY = 'abc'

but it's not helping me
