Python Functions Emulator raises an error when path has spaces

[aalej]

When trying to start the Cloud Functions emulator that uses Python, an error is being raised when the path has spaces. An error is also raised when trying to deploy.

[REQUIRED] Environment info

firebase-tools: 12.0.0

Platform: macOS

Node: v18.15.0

Python: v3.11.3

[REQUIRED] Steps to reproduce

1. Run mkdir 'i like spaces'
2. Run cd i\ like\ spaces or cd 'i like spaces'
3. Run firebase init functions --project <project_id>
   1. Select Python
   2. Do you want to install dependencies now? Yes
4. Run cd functions
5. Run firebase emulators:start
   1. Error is raised.
6. Uncomment code in main.py to deploy
7. Run firebase deploy --only functions
   1. Error is raised.

Notes:
No issues are raised running either firebase emulators:start or firebase deploy commands when using a path that has no spaces. Replace steps 1 & 2 from above with:

1. Run mkdir 'no-spaces'
2. Run cd no-spaces

[REQUIRED] Expected behavior

Functions emulator to start without any issues and functions to deploy without any issues.
