Python and virtual enviroment

Hi, I am a newbie at Linux For me HASS.IO sholud be the easiest way to start with Home Assistant, but one requirement is to run this addon:
I was not able to run theese commands (sudo pip3 install pyserial &
sudo pip3 install datetime & sudo pip3 install pyserial_asyncio) in HASS.IO and therefore I installed Hassbian instead - but when I try to do according to the instruction HA displays a error message “Visonic component could’t be found”
I have done som googling and I guess it has someting to do with python and virtual ennviroment?
Can I use HASS.IO and install this addon? - How?
