Roomba / Python / HA OS

Hey all,

I’ve got HA installed on a x86 system.
I am trying to add the iRobot integration, which asks for a password.
Following the links i land here:

or

When i try the first instructions for install ( link 1 )
$ npm install dorita980 --save
it sais npm not recognized.

When i try the instructions of the link 2
It sais i dont have python installed.

I’m kind of stuck on how to get the password this this integration.
I previously had a Docker installation of HA and it didnt ask for any password. ( change the wifi setup in the meantime, swapped routers )

Anyone have any advice on how to proceed?
Thanks,
