Failure to npm install because of gulp-sass version

[radu-m]

Trying to install the boilerplate on Ubuntu 15.10 fails with the output below because of the gulp-sass version specified in package.json

I've fixed the issue by removing the node_modules dir from my project, changed the gulp-sass version from "gulp-sass": "^0.7.1" to ^2.0.1 and did a fresh npm install after.

It took me a while to figure it out, so I hope this will be helpful for others.
