Node: npm installation broken

[eliyastein]

I'm not sure when this fell apart, but I'm experiencing this:

````$ npm -v
module.js:545
throw err;
^

Error: Cannot find module '../lib/utils/unsupported.js'

I tried updating, then uninstalling, then re-installing node with homebrew.

$ uname -a Darwin Ricos-MacBook-Pro.local 16.7.0 Darwin Kernel Version 16.7.0: Thu Jan 11 22:59:40 PST 2018; root:xnu-3789.73.8~1/RELEASE_X86_64 x86_64

Does anyone know how to troubleshoot this?

Could you also try to post the issue to the npm repository?

Will do! Thanks @vsemozhetbyt

I finally got this fixed:

• brew uninstall node

• manual rm of the npm binary which was lingering

Then did the following:

$ sudo chown -R $USER /usr/local
$ brew postinstall node

npm now finally works!
