Installing Node Sailsjs package with NPM

I want to install SailsJs using Node Package Manager.

https://github.com/balderdashy/sails-docs/blob/master/getting-started/getting-started.md

I try to install with the below command on terminal -

sudo npm -g install sails

But it fails with an error -

npm ERR! Error: ENOENT, open '/Users/.../node_modules/sails/node_modules/grunt-contrib-watch/node_modules/gaze/package.json'

Seems like there is some problem with the gaze package.

And I am not sure how to fix this. The full error stack is here -

Please help me with a way to fix this.

Try sudo npm install -g npm to update your npm version and try to npm cache clean
