Google API Python Client Import Issue

Anki Development
1

Hey,
I’m having some issues getting the google-api-python-client to work on Anki.

I installed the necessary packages with pip to a target folder inside the Anki Add-Ons Folder and added the dist Folder to the sys path like I do with any other third party package.

In the following example:
pip install -t . functional google-auth google-auth-httplib2 google-api-python-client --upgrade

It works fine for other packages I tested, but appears to break on googles even though it gets properly installed.

A minimal example would be this:

AddOnFolder/
AddOnFolder/dist/
AddOnFolder/main.py
AddOnFolder/init.py

main.py looks like this:

import os
import sys

sys.path.insert(0, os.path.join(os.path.dirname(__file__), "dist"))

import functional
import google.oauth2

I only added the functional to show that other packages work fine from the same folder.

Now what puzzles me is that when I run the same main.py as a standalone and not via anki, it works fine so I don’t believe it’s a missing dependency or path issue. Only when I let Anki run the main it fails with the error:
(Note that it accepts the functional import in the line above just fine).

main.py", line 7, in <module>
    import google.oauth2
ModuleNotFoundError: No module named 'google.oauth2'
<U+2069>

I believe it is caused by the fact that the Anki Directory Anki/lib/ contains a folder called google and thus interferes with the import of the google package in dist/google/ since it’s used as a search path.

I thought adding the dist/ path at the front of the sys.path would solve it (since python checks in the directories in sequential order), but it doesn’t.

Renaming the dist/google/ to something else and changing the import google.oauth2 to the new name works, but causes more issues down the line since the google api itself uses imports from google.x , too.

I’m honestly not sure how to approach this issue or fix it and would greatly appreciate any help or guidance.

I once had a similar problem when trying to use the google-cloud-texttospeech module in an add-on. I don’t remember the exact details of the problem, but something like this worked for me:

sys.path.insert(0, os.path.join(addon_path, "vendor"))
google_path = os.path.join(addon_path, "vendor", "google")
source = os.path.join(google_path, "__init__.py")
spec = importlib.util.spec_from_file_location(
    "google", source, submodule_search_locations=[]
)
module = importlib.util.module_from_spec(spec)
sys.modules["google"] = module
spec.loader.exec_module(module)
del sys.modules["google.protobuf"]

from google.cloud import texttospeech

(I might be wrong and your problem could be different though)

This is amazing. Not sure why, but your snippet did the trick for me too.

Thanks a lot for your help. You saved me hours of debugging <3
