Can anybody explain how correctly to set up firebase-functions with Python?
My current steps:
-
create “blank workspace”
-
run firebase init functions-> that create “functions” folder as it should but no “venv” is created (and because of that no dependencies are installed) -> not case for the guy in this video
-
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 initagain 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 but only that can fix the issue)
-
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 addnumpylibrary 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 (because I changed to python312 in packages?):
