nvm turned out to be more of a pain in the ass as one thing after another went sideways - for one, it appears to be hellbent on using gcc and no matter how specific Grok & I got in running configure, it just refused to accept to use clang. I’m not installing gcc.
So I completely cleaned up and in my usual caveman style, ripped out all node, node-npm and all user level config directories and reinstalled node, node-npm, yarn and ghost-cli …
… now running a most squeaky clean server I’ve had yet. AND ghost-cli, for some reason, is now at version 1.27!
Mission accomplished - LOL
