[Solved] OSX: Problem installing node-red@0.20.0 beta

(a good deed never goes unpunished)
macOS High Sierra 10.13.6

So this morning I decided to install NR 0.20.0 beta 5 (first time installing 0.20.0) to test a bug I reported back in December marked 'fixed'.

So I user sudo npm install -g --unsafe-perm node-red@next and all hell broke loose. The install fails:

Pauls-mini-3:.node-red Paul$ sudo npm install -g --unsafe-perm node-red@next

When I go look at /tmp/npm-95562-60ca229c it is empty, so nothing has been unpacked into it. If I look at it's ownership I see it is owned by root/wheel

Any ideas??

Well, after some google searching, I finally blew away all my node directories and reinstalled node.js (which brought me to v10.15.1) and I was able to reinstall node-red.

Well that was fun (not)

Interesting. Did you (or someone in the Googleverse) get to the bottom of the problem? I installed the beta 5 with node.js v8.11.2, no issues.

I forun several ideas in the Goolgeverse and went in and hand removed all the 'node' occurrences in various libraries. That allowed me to reinstall node.js and tehn installing NR worked.

It was probably because of something I have done to my machine since I originally installed NR many many moons ago and I have no idea what it could have been. Since it is now working, I won't be looking at it (till the next time I try to upgrade - grin)
