Google Calendar Error httplib2

[fastie81 (CVR)]

Hi

I am trying to setup Google Calendar integration. When I add my config to configuration.yaml and test the the config I get the following error. Most of the things I am seeing is to install httplib2 via pip, but it does not look like I can do that easily on hassio on a rpi4.

Integration error: google - Requirements for google not found: ['httplib2==0.19.0'].

My config

google:
  client_id: !secret google_id
  client_secret: !secret google_secret

I am following the process outlined here…

Google Calendars

Any help would be much appreciated.
my home assistant version.

Thanks
