npm run dev throws an error

[gnesher]

Just did a clean install (cloned repo, installed dependencies and ran npm run dev) I'm getting the following error which isn't very helpful:

(node:4041) UnhandledPromiseRejectionWarning: Error: Exited with code 3

The demo does load and I can't tell exactly what's broken - but it's a little disconcerting

This is a bug with opn. Since it's difficult to debug as it's relevant to node version and your OS, I recommend you look for autoOpenBrowser in /config/index.js and set it to false.

@bala223344 this is an issue with opn. You have a better chance to solve this to open an issue there.
