Error when running Ionic serve in Ionic 2

fatal: cannot create directory at 'node_modules/...'

@bkcollection I think that installing the latest version of NPM should resolve the problem because it uses a flat directory structure, check out the linked topic for details:

I was having these problems with Windows and long file names etc however installing the latest npm fixed the issue because version 3 onwards I believe (and as Mike Hartington has also commented) creates a flat dependency tree structure for node modules.
