I broke Node-red by upgrading to Node 23

General
1

I goofed up big time. I upgraded node to 23 and I am getting errors with Node-red running... So I tried to purge node or downgrade and I am getting issues running the install script ( Pi ).

What can I do to flush everything out, node wise on this server and get a fresh install of Node-red? I'm going down a rabbit hole of debuggery here...

This can take 20-30 minutes on the slower Pi versions - please wait.

  2. Run the installer with --node22 on the end
