I found a GitHub repo for reference and practice but when I'm trying to run it on my system it is giving me this error:

Traceback (most recent call last):
  File "C:\Users\Nikita\Desktop\GitHub files\HomieChat-main\homiechat\manage.py", line 22, in <module>
    main()  File "C:\Users\Nikita\Desktop\GitHub files\HomieChat-main\homiechat\manage.py", line 9, in main

    raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option))
decouple.UndefinedValueError: LOCAL_SETTINGS_MODULE not found. Declare it as envvar or define a default value.

I can't understand what this error means. I installed the requirements.txt but it's the same. On searching the project for LOCAL_SETTINGS_MODULE, I found: os.environ.setdefault('DJANGO_SETTINGS_MODULE', config('LOCAL_SETTINGS_MODULE')) in settings.py, asgi.py, and wsgi.py.

I need to understand what this LOCAL_SETTINGS_MODULE is and how to fix this error.
