I installed this on a different machine about six weeks ago (Ubuntu-Mate 18.04) and it worked. No idea what has gone wrong here. I hope there is a quick solution.

The cb() error you are seeing has a thread over here: [crash] npm ERR! cb() never called!

There’s a Canary build that should give you a more descriptive error to try to better pinpoint the actual issue.

I’m not making any sense about that"canary" thing, but the thread you linked mentioned “too many open files”. I was running a large make and trying to setup node-red while waiting for it to complete.

Now that the compile completed ,I tried again and it installed.
