  1. ImportError: No module named 'django' Solution: You need to install Django using pip or any package manager you prefer.

  2. ModuleNotFoundError: No module named 'mysite' Solution: Make sure that your project directory is in the PYTHONPATH environment variable and it contains a file named "manage.py".

  3. ImportError: cannot import name 'settings' from 'mysite' Solution: Check if the settings.py file exists in the correct location. If not, create a new one and make sure that it is properly configured for your Django project.

  4. AttributeError: 'module' object has no attribute 'WSGIRequestFactory' Solution: Make sure you have installed Django REST Framework. If not, install it using pip: "pip install djangorestframework".

  5. Error while running python manage.py runserver : command not found Solution: Make sure that the PYTHONPATH environment variable is correctly configured and that the Django package is installed in your system.

  6. ImproperlyConfigured: AUTH_USER_MODEL refers to 'auth.User', which has been removed. Specify AUTH_USER_MODEL as 'yourappname.YourModelName' instead. Solution: Make sure that the AUTH_USER_MODEL setting is correctly configured in your settings.py file.

  7. OperationalError: (1045, "Access denied for user 'username'@'localhost' (using password: YES)") Solution: Check if the username and password you are using to connect to MySQL are correct and that the user has enough privileges to access the database.
