seems it could be some sort of python deps issue.. I've switched from pip to pip3 .. but maybe

pip3 install meltano

needs to have some sub-dependencies pinned differently? I cannot recreate the bug easily nor understand the error other than it's related to

markdown.extensions

on install I see these warnings.. but Meltano seems , in this run of the installer at least.. to get going and I can load the UI

IMO, docker adds a lot of value.. when you know what you’re building

when I am experimenting, or testing.. I prefer something simpler

anyway I figured it out.. it turned out something deep in python pypi had changed and I think I’ve successfully cleaned up things so far..

I will test next week with this user I am demoing meltano with..
