I can run my web app on my local machine - no errors. But when porting the directory strcture to Azure, I get the ModuleNotFoundError: No module named 'django'. Here is what I did: My app is publicly available on GitHub. The app runs in a virtual environment (called deploydjango). That is reflected in the tree structure of the repo.

Django Web App running on local Debian 10 but failing on Azure

I can run my web app on my local machine – no errors. But when porting the directory strcture to Azure, I get the ModuleNotFoundError: No module named 'django'.

Here is what I did:

My app is publicly available on GitHub. The app runs in a virtual environment (called deploydjango). That is reflected in the tree structure of the repo.
I ensured that Python version was correct (3.8 as on my local machine).
I posted the code to Azure (using the Azure extension of Visual Studio Code).
When browsing to the web app URL, I get the error message:

:( Application Error
If you are the application administrator, you can access the diagnostic resources.

That takes me to Diagnose and solve problems on Azure page for the Web App Service. Here I find Availability and Performance.
- Herein the tab “Web App Dow” is found.
  - Under Application Logs I am advised, that: Application logs from instance: lw0sdlwk00016P contain an error or a warning
  - Clicking More info, I get a log telling me:

above two lines says Django is not installed

If it is installed then check the below documentation:
