NPM install -g not working after Titanium install

I have installed Titanium onto my mac and now when ever I try to globally install any npm packages it fails.

The output from my install is

npm http 304 https://registry.npmjs.org/loggly
npm http GET https://registry.npmjs.org/underscore
npm http GET https://registry.npmjs.org/timespan
npm http GET https://registry.npmjs.org/request
npm http 304 https://registry.npmjs.org/underscore

└── prompt@0.1.12 (async@0.1.22, pkginfo@0.3.0, winston@0.5.11)

When I then subsequently do which grunt-init, nothing is returned. It seems like something which is part of Titanium is interfering with my -g npm install?

This only started happening since I installed Titanium. I can get it working if I manually install grunt-init in the npm directory, but this has literally taken away the best feature for me.

please help!
