setting up firebase-functions with Python

[neo-xy]

For the love of anything that is holy and unholy can anyobdy explain how correctly to set up firebase-functions with Python?! 😤😭
(tested everything that I found on stackoverflow and chatGpt/gemini to set it up but one error just leads to another and I just spinning in the circles for 3 days now -.-)
At this point I abandon to build it localy and trtying to use "project idx" instead (as my local envirment is trash at this point after all AI sugestions).

##my current steps:##

• create "blank workspace"

• run firebase init functions-> that create "functions" folder as it should but no "vevn" is created (and because of that no dependecies are installed)-> not case for the guy in this video :/ -> https://www.youtube.com/watch?v=mvEHYMsk_AE&t=202s

• cd functions -> python3 -m venv venv -> pick "python3" in list (as sugest by gemini) -> instalation completed

• adding "pkgs.python3" to dev.nix -> packeges

• test runing firebase init again to install missing dependecies (now when I have venv in functions) but getting error: Requirement already satisfied: pip in ./venv/lib/python3.11/site-packages (24.0)
  /bin/sh: line 1: python3.12: command not found

• so bc of that I go to dev.nix and change in packages from "pkgs.python3" to "pkgs.python312" (keep in mind that docs says that python 3.10 and 3.11 are supported)

• run firebase init again and only now all the dependecies are installed

• I can now deploy functions as well
  BUT let's say that I want to add numpy library to project:

• when in "/functions" directory : source venv/bin/activate

• pip install numpy -> python311Packages.pip

• import numpy to the project, ex:

from firebase_functions import https_fn
from firebase_admin import initialize_app
import numpy as np

initialize_app()

https_fn.on_request()
def on_request_example(req: https_fn.Request) -> https_fn.Response:
    np.random.seed(42)
    return https_fn.Response("Hello world!")

• run firebase deploy, now I get this error (bc I changed to python312 in packages??):

Error: Functions codebase could not be analyzed successfully. It may have a syntax or runtime error

then I tested some things to fix that error (founded on stackoverflow and AIs but nothing helped/leaded to som eother errors)
It's just like there is no wining with this s*** 😫

(please keep in mind that I'm not a python developer and for all Python pros that is maybe a silly fix-although I ask some of my colleagues that code in python and they could not fix it for me:/ )

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hello @neo-xy. Have you followed the instructions here?

[neo-xy]

Hi @exaby73 yes, I did - and the big thing that is missing there (that I noticed just yesterday) is that one have to run pip freeze -> requirements.txt FROM /fanctions directory before firebase deploy- which is missing in documentation (at least of what can I see). at the same time so still don't understand why "firebase init" in the attached youtube video creates "venv" but when I run it it does not ....

[exaby73]

I see the venv folder being generated under functions/venv on running firebase init and choosing Python. I'm using version 13.11.4 of the CLI. Make sure you have your CLI updated by running npm install -g firebase-tools@latest
