Python Functions emulator fails with space in project directory path

[benbrunyee]

[REQUIRED] Environment info

firebase-tools: 12.0.1

Platform: Windows

[REQUIRED] Test case

1. Create a directory with a space e.g., `C:\Users\name\Desktop\project directory\
2. Run firebase init functions and run through the setup for Python functions.
3. Fix any pip version errors you get and re-run firebase init functions to get dependencies installed
4. Run firebase init emulators and setup the functions emulator
5. Run firebase emulators:start and see error below:

bruny:vite-project$ firebase emulators:start
i  emulators: Starting emulators: functions
!  ui: Emulator UI unable to start on port 4000, starting on 4001 instead.
!  functions: The following emulators are not running, calls to these services from the Functions emulator will affect production: auth, firestore, database, hosting, pubsub, storage
i  ui: Emulator UI logging to ui-debug.log
i  functions: Watching "C:\Users\bruny\Desktop\project directory\vite-project\functions" for Cloud Functions...
!  functions: Failed to detect functions from source FirebaseError: User code failed to load. Cannot determine backend specification.
stderr:C:\Users\bruny\AppData\Local\Programs\Python\Python311\python.exe: can't open file 'C:\\Users\\bruny\\Desktop\\project': [Errno 2] No such file or directory

!!  functions: Failed to load function definition from source: FetchError: request to http:https://127.0.0.1:8081/__/quitquitquit failed, reason: connect ECONNREFUSED 127.0.0.1:8081

[REQUIRED] Steps to reproduce

(More environment info)
yarn --version = 1.22.19
vite --version = vite/4.3.3 win32-x64 node-v16.13.2

1. Create a directory with a space e.g., `C:\Users\name\Desktop\project directory\
2. Create a SveltKit vite project in the above directory with yarn create vite. Select SvelteKit and TypeScript as the options. The project name here does not matter
3. Run firebase init functions and run through the setup for Python functions.
4. Fix any pip version errors you get and re-run firebase init functions to get dependencies installed
5. Run firebase init emulators and setup the functions emulator
6. Run firebase emulators:start and see error below:

bruny:vite-project$ firebase emulators:start
i  emulators: Starting emulators: functions
!  ui: Emulator UI unable to start on port 4000, starting on 4001 instead.
!  functions: The following emulators are not running, calls to these services from the Functions emulator will affect production: auth, firestore, database, hosting, pubsub, storage
i  ui: Emulator UI logging to ui-debug.log
i  functions: Watching "C:\Users\bruny\Desktop\project directory\vite-project\functions" for Cloud Functions...
!  functions: Failed to detect functions from source FirebaseError: User code failed to load. Cannot determine backend specification.
stderr:C:\Users\bruny\AppData\Local\Programs\Python\Python311\python.exe: can't open file 'C:\\Users\\bruny\\Desktop\\project': [Errno 2] No such file or directory

!!  functions: Failed to load function definition from source: FetchError: request to http:https://127.0.0.1:8081/__/quitquitquit failed, reason: connect ECONNREFUSED 127.0.0.1:8081

[REQUIRED] Expected behavior

The functions emulator should be able to handle spaces in directory paths.
This should work in Git Bash, CMD, PowerShell

[REQUIRED] Actual behavior

The emulator fails to run unless I modify the path to remove the space.
This is the case when running using Git Bash, CMD and PowerShell

Hi @benbrunyee, thanks for reporting this issue. I was able to replicate the behavior you mentioned using firebase-tools v12.0.1 on a macOS machine by following steps similar to the one provided in your test case:

1. Create a directory with a space
2. Run firebase init functions and run through the setup for Python functions.
3. Run firebase init emulators and setup the functions emulator
4. Run firebase emulators:start

That said, I’ll notify our team about this so that we can investigate this issue. I'll also be marking this issue as reproducible.

The issue should be resolved in the next release. Thank you for reporting the issue!
