How to install hue-thief on Rpi2 + HassOS?


I am having issues with adding Philips Hue bulbs after I removed them from HA.
I don’t have a bridge, so I read that you can use hue-thief to factory reset the bulbs.
But I have no clue how to install hue-thief on my Rpi2 + HassOS.
I logged in via ssh and tried to run python but it’s not installed it seems.

How would I go about doing this?
