Configure build for needed platforms

[B4tzz]

Hi,

I'm trying to deploy an app to an Azure App Service using local Git deployments through VS Code. The App Service runtime is set to Python 3.11, but I also need Node.js 20 for the frontend build. However, Oryx sometimes detects the Node.js platform but installs version 16 instead. How can I specify the exact version I need?

Another issue I'm facing is with a dependency for a Python library. My project requires PyAudio. Locally, pip install works fine, but during the build process, it fails with an error saying it can't find the portaudio.h package. From my research, I learned it depends on a C library called portaudio19-dev. I tried installing it using pre-build commands, but that also failed.

How can I resolve these issues?
