Error on npm install

[Sebastian Sandqvist]

Each time I attempt to install zuul from NPM, I get an error message. I've tried with various npm and node versions, but the following results are from node (iojs) v3.1.0 and npm v2.13.3

npm i -g zuul

> fsevents@0.3.8 install /usr/local/lib/node_modules/zuul/node_modules/watchify/node_modules/chokidar/node_modules/fsevents
> node-gyp rebuild

seems like something failed when downloading from npm. Maybe clear your npm cache npm cache clean
