Deployment Failing: Error Persists with Old Repo Name After Renaming (Could not find root package)

Hello Streamlit Community,

I’m facing a persistent issue while deploying my app on Streamlit Cloud and I’m hoping someone can help diagnose it, as standard troubleshooting steps haven’t worked.

The Problem:

My app deployment fails during the dependency processing stage with the error:

error: Could not find root package `teachers-arrangement-system`
[Timestamp] ❗️ installer returned a non-zero exit code
[Timestamp] ❗️ Error during processing dependencies! Please fix the error and push an update, or try restarting the app.

Use code with caution.

Context & Steps Taken:

  1. Initial Error: I first encountered an error related to main.py not being found. I corrected my repository structure so that main.py is now at the root level.

  • GitHub Repo: https://github.com/rishi9520/teacherarrangement (Initially named teachers-arrangement-system)

  • main.py is confirmed to be at the root.

  • requirements.txt is also at the root, and I’ve fixed a duplicate entry (streamlit-authenticator).

  1. Persistent Dependency Error: After fixing the file path, the Could not find root package ‘teachers-arrangement-system’ error started appearing.

  2. Repository Renaming: Suspecting the hyphen (-) in the original repository name (teachers-arrangement-system) might be causing issues with the build process, I renamed the repository on GitHub to teacherarrangement.

  3. Re-deployment:

  • I deleted the old app on Streamlit Cloud associated with the old repository name.

  • I created a new app deployment, explicitly selecting the new repository name (teacherarrangement).

  • Deployment settings used:

    • Repository: rishi9520/teacherarrangement

    • Branch: main

    • Main file path: main.py

    • Python Version: Tried 3.12, also tried 3.11 on re-deploy.

The Core Issue:

Despite renaming the repository, deleting the old app, and deploying afresh using the new repository name (teacherarrangement), the deployment logs still show the error referencing the old repository name : Could not find root package ‘teachers-arrangement-system’.

Here are the relevant logs from the latest attempt (using the new repo name teacherarrangement):
