[drbe4t]

Soo i'm not quite sure what's going on. firs it gives me this.

npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated tough-cookie@2.2.2: ReDoS vulnerability parsing Set-Cookie https://nodesecurity.io/advisories/130

I had the same error on Mac and also on Linux, it was not just with roots, when I was installing Gulp it happened too, type this on terminal, it worked for me:

npm config set prefix '~/.npm-packages'

and adding $HOME/.npm-packages/bin to $PATH

export PATH="$PATH:$HOME/.npm-packages/bin"

If it doesn't work, check this: #725

Yep #725 has the answer!
