Exit status 2 on "npm run dev"

Hi,

First of all thanks for laravel-mix. However I can’t get it to work.

My steps:

1. npm install
2. Updated node and npm to latest versions
3. Update laravel-mix to 0.5.1
4. Updated webpack.mix.js to match the fix branch on the Laravel repo

Every time I run npm run dev I get the below error. Any idea what it could be?
