Errors installing Yo and while using angular generator - node.js

Question

I am trying to install Yeoman using NPM, but am greeted by the following error:
Jaspers-MacBook-Pro:Sites Jasper$ sudo npm install --global yo
> fullname-native#0.1.1 install /usr/local/lib/node_modules/yo/node_modules/fullname/node_modules/fullname-native

[Yeoman Doctor] Everything looks alright!

Since Yeoman doctor says "looks allright", I tried to install te angular generator
npm install -g generator-angular
yo angular
This just returned some more errors:

I've tried to update node-gyp, uninstalled node and reinstalled via homebrew but with no success...
if I install the generator with sudo, running yo angular returns the following

Don't see why this isn't working, as I had it working before
I'm on a clean install of OSX Mavericks

I had a similar issue. Get started with fixing the permissions issue:
sudo chown -R `whoami` ~/.npm
sudo chown -R `whoami` /usr/local/lib/node_modules
It's a popular issue: npm throws error without sudo
