Cannot start hass


#1

Since I updated from 0.75.1 to 0.81.5 and I start hass I get the following error:

Anyone has any idea how to fix this?
I’m running a manual installation of hass on a raspberry pi 3

This feels like you do not have sqlalchemy installed on the version of python that you are running HA.
