Why can't I install primabase onto blender addons

When i try to install the primbase addon into blender it wont work, and everytime
I do it I get an error like this
helpp

if anybody can point out to something I’m doing wrong or I need to do, would greatly appreciated

Maybe it was made three years ago for blender 2.8… and there where some changes in 2.9 (which you seems to use)??

Also the original addon is “talking of” addon vers 2.0.2 and this fork of 2.6.1

So you might have more luck with this ???

Also the “original” thing for this was made for… is abandomed ???

Never assume a plugin is compatible with any blender version you throw at it
