Shoutem Install Error - node.js

Question

I am trying to follow the steps listed here but keep getting an error when trying to install shoutem-cli - $ npm install -g #shoutem/cli
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! ngrok#2.2.21 postinstall: `node ./postinstall.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the ngrok#2.2.21 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional log ging output above.
npm ERR! A complete log of this run can be found in:
npm ERR! /root/.npm/_logs/2017-08-24T13_20_31_973Z-debug.log
The log file can be found here.
If you need more info, please let me know.
I tried searching for these errors or common issues and had 0 luck so I'm not sure where to begin. Any help would be greatly appreciated.
Thanks!

This seems to be related to ngrok#2.2.21 postinstall script. Doing a quick investigation, there seems to be some Ubuntu related issues - here. From what I can tell it seems to be permission related. We'll try to find a working version and restrict our CLI semver until this is resolved, we've already published the new version of CLI which restricts ngrok to 2.2.17 in an effort to resolve this (CLI version 0.9.4 - just run again npm install -g #shoutem/cli). We're using ngrok to ease up connections between React Native packager on your development machine and your phone.
