How to Fix this Issue

Here are some steps to fix this error:

  1. First, check if you have the correct module installed on your system.
  2. If not, use pip or another package manager to install it.
  3. Make sure your Python version is correct for the module you are trying to use.
  4. Check your settings in your code.
  5. If you recently moved files or folders, update all import statements.
  6. Restart your environment and try running the code again.

Common Mistakes that Cause This Error

  • Trying to import a module that doesn’t exist.
  • File structure is not set up properly.
  • Using the wrong Python environment or version.
  • Missing dependencies or packages.

How to Prevent This Issue in the Future

One good way to avoid this kind of error is to keep your project files organized. If you are using Django or Flask or any other framework, make sure that all apps are in the right folders. Check that your “init.py” files are there if needed. 

Also, always test your code in a clean environment to catch errors early. Keeping your Python environments separated using tools like virtualenv or conda can also help avoid mix-ups.
