Google Gmail API, works fine as .py but throws "googleapiclient.errors.UnknownApiNameOrVersion: name: gmail version: v1" when ran as .exe

Question

The code runs perfectly in Pycharm, or when running the .py file but I need the app to be a .exe file to be ran on devices without python.

I am trying to allow a user to report a bug/give feedback in the app from a tkinter window. The feedback is then sent to me via the gmail-api.

The .exe file is made from pyinstaller (being ran from inside the virtual environment) When running the exe file everything works fine up until:

service = build(serviceName='gmail',
                        version='v1',
                        credentials=creds,
                        discoveryServiceUrl="https://gmail.googleapis.com/$discovery/rest?version=v1")

Where it produces

  File "googleapiclient\_helpers.py", line 134, in positional_wrapper
  File "googleapiclient\discovery.py", line 273, in build
  File "googleapiclient\discovery.py", line 387, in _retrieve_discovery_doc
googleapiclient.errors.UnknownApiNameOrVersion: name: gmail  version: v1

The code below is executed when a tkinter button is clicked.

The gmail code is almost completely copied from the google gmail api example.

Small code snippet:

from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
SCOPES = ['https://www.googleapis.com/auth/gmail.send']
def process_report():
        creds = None
        if os.path.exists('token.json'):
            creds = Credentials.from_authorized_user_file('token.json', SCOPES)
        # If there are no (valid) credentials available, let the user log in.
        if not creds or not creds.valid:
            if creds and creds.expired and creds.refresh_token:
                creds.refresh(Request())
            else:
                flow = InstalledAppFlow.from_client_secrets_file(
                    'client_id.json', SCOPES)
                creds = flow.run_local_server(port=0)
            # Save the credentials for the next run
            with open('token.json', 'w') as token:
                token.write(creds.to_json())

        service = build(serviceName='gmail',
                        version='v1',
                        credentials=creds,
                        discoveryServiceUrl="https://gmail.googleapis.com/$discovery/rest?version=v1")

        msg = create_message("sender_email@gmail.com",
                       "reciever_email@other.com",
                       subject, message)

        send_message(service, "me", msg)

Any help or suggestions is much appreciated.

Resolved the issue by reverting the google-api-python-client to 1.8.0

pip install google-api-python-client==1.8.0
