I am getting this error every time I initiate firebase functions with python

python --version: Python 3.13.3

OS: window 11

pip --version: pip 25.1.1 from C:\Python313\Lib\site-packages\pip (python 3.13)

firebase-debug.log shows

Hi @aqibnawazdev

I believe I've seen this issue before. I imagine this would be a firebase-tools problem, but I'll have a look.

I fixed this issue by installing dependencies after initialization.

I can confirm, using the latest version of firebase-tools, I also receive this error on Windows. On Mac, I don't seem to have any issues.

I know there have been a lot of issues in the past with Windows, so perhaps this is just another one. Are you also using Windows?

For now, I will move this issue to firebase-tools, as I believe this is an issue there.

Yes, I am using window 11

I think its a problem with firebase-tools/lib/functions/python.js as venv activate.bat doesn't work in powershell anymore. Probably needs to be replaced with Activate.ps1. If you manually replace, the firebase init functions command does run, but it opens an editor with Activate.ps1 (so you'll need to check how the command is launched as well.)

Any solution for this?

Just figured out the issue, check the pyvenv.cfg file in the venv folder. Ensure it points to your main system Python. If not remove the the wrong path or reorder the path in the Environment Variables. This seems to fix the issue for me (mine was pointing to Inkscape python.exe)
