I tried D:\CodeSpace\Azure\azure-search-openai-demo\scripts\.venv\scripts\python.exe -m pip install cffi but not working in this method, again I will get same issue...

I have this same issue once I moved to a new laptop.

Try adding cffi to requeriments

According to this, you might need also: paramiko and cryptography

After you add the libs to requeriments, delete the .venv folder and run prepdocs.ps1 again

I tried to run the project in VS code locally, but I have similar issue but the module that I missed is quart, I have added quart in /app/requirements.txt, /scripts/requirements.txt, but none of them worked, I have manually install via pip install, still useless, anyone know how to fix this?

@Pancat007 Are you using a virtual environment or VS Code? Can you share the full results of running ./start.sh? That should have installed quart for you, so I'm curious if there are any errors there. What Python version are you using?
