Troubleshooting ModuleNotFoundError: No module named 'guide' in Django

When setting up your Django web server, especially on an AWS Ubuntu machine, you may encounter errors that can be frustrating for beginners and experienced developers alike. One such error is the infamous ModuleNotFoundError: No module named 'guide'. This guide aims to decipher this issue and provide you with a clear guide to resolve it effectively.

Understanding the Problem

The error message suggests that Python cannot find the module named guide, which is likely your Django project name. This typically happens due to a misconfiguration in your project structure or environment. Additionally, the HTTP 500 internal server error indicates that something went wrong on the server side, perhaps due to an incorrect setup.

Log File Review

In your error log, you noted several lines indicating that the WSGI server failed to execute the Python script located at /home/ubuntu/django-project/src/guide/wsgi.py. The problem often stems from how you've structured your Django project's folder or how you configured your WSGI settings.

Analyzing Your Project Structure

To check and fix this issue, let's evaluate your current folder structure against the standard layout recommended by Django:

As you can see, the guide directory is nested within another guide directory. This nesting is important because it directly influences how Python locates the modules.

Correcting the Configuration

To resolve the ModuleNotFoundError, you need to adjust your WSGI configuration in the Apache .conf file to reflect the correct path to your wsgi.py file. Here’s what you should do:

Update Your Apache Configuration

Find the default000.conf file in your Apache configuration and make the following changes:

Conclusion

By understanding the underlying reasons for the ModuleNotFoundError: No module named 'guide', you should be able to fix the issue quickly and streamline your Django development process. Clean folder structure and proper WSGI configurations are vital to ensure your application runs smoothly on an AWS Ubuntu environment. Happy coding!
