Describe the results you expected

Working npm@5.3.0

What version of npm you are using

No node/npm installed previously, only through n 8.2.1 and n 4.1.2

Additional information you deem important (e.g. issue happens only occasionally):

Could those invalid packages leftovers from node 4.1.2/npm 2.14.4 ( #403 )? Can't update npm myself.
npm install -g npm@latest

Probably related to/duplicate of #310.

Try reinstall npm:

$ curl -0 -L https://npmjs.com/install.sh | sudo sh

You might not need sudo

If doesn't work still, try re-install node.
If you installed node with brew, try:

$ brew uninstall node
$ brew install node

If you still having issues after that, try this solution

I tried the steps @leocaseiro suggested, but that didn't work for me. Oddly re-installing it from the GUI worked (https://nodejs.org/en/download/) -- which installed version Node v8.11.1, NPM 5.6.0. For reference I'm on OSX 10.12.6.

Just wanted to add this comment in case it helps others resolve this issue!
