don't know python very well either. It just won't work.
Edit: Nvm, didn't know the first known issue is related to this error
---------
btw if you don't know anything here's how to use it:
install python 2.7._
open window's cmd prompt
type pip install jinja2 and then press enter
type cd, a space, then the location of the folder then press enter (e.g cd C:\scriptz\ck2autobuild-19-1a)
type py generate_auto_build.py then press enter
wait until it finish
go to output folder\autobuildexamples\ and copy and paste anything inside that folder to ck2 mod folder (C:\Users\yournamehere\Documents\Paradox Interactive\Crusader Kings II\mod)
activate the mod in the game launcher
Additional info:
if you have python 3._._ installed too:
use py -2.7 -m pip install jinja2 instead.
use py -2 generate_auto_build.py instead
If you have no such file or directory error refer above
