WinError 10013 when trying to create calendar object

[neurognome]

I think this is potentially due to either attempting to run this on a computer that's managed by my organization or something, but when I try to just run the first line to instantiate a "calendar" object, I get this error:

Traceback (most recent call last):

I think the problem is that google_auth_oauthlib runs its authentication flow server on the port 8080 by default which might be occupied by something else in your system.

Try netstat -a -b -n and check if this port is in use. If you can, quit the application that uses it. If not it would require overriding the _get_credentials of GoogleCalendar like so:

class GoogleCalendarOnAnotherPort(GoogleCalendar):    
    def _get_credentials(self):
        _credentials_path = os.path.join(self._credentials_dir, self._credentials_file)

        credentials = None

        if os.path.exists(self._token_path):
            with open(self._token_path, 'rb') as token:
                credentials = pickle.load(token)

        if not credentials or not credentials.valid:
            if credentials and credentials.expired and credentials.refresh_token:
                credentials.refresh(Request())
            else:
                flow = InstalledAppFlow.from_client_secrets_file(_credentials_path, self._scopes)
                credentials = flow.run_local_server(port=8090) # note the port parameter. Change to any free port

            with open(self._token_path, 'wb') as token:
                pickle.dump(credentials, token)

        return credentials

It is a workaround and should be fixed in the future version of the gcsa.

Thank you for the issue submission.

Perfect! That was exactly the issue, I set it to use a different port and everything is working great.

Thanks so much.

I'll leave the issue open until it is fixed in the implementation
