When I tried the quickstart.py example, I ran into the following error

run_flow() missing 1 required positional argument: 'flags'

This can be fixed by adding a call to tools.argparser.parse_args and including the returned flags in the run_flow call:

flags = tools.argparser.parse_args(args=[])

if not creds or creds.invalid:
    flow = client.flow_from_clientsecrets('client_secret.json', SCOPES)
    creds = tools.run_flow(flow, store, flags)
