When I try to run this command -- npm -v , I get the following crap on the mac command line

node.js:134
        throw e; // process.nextTick error, or 'error' event on first tick
        ^
TypeError: Cannot call method 'apply' of undefined

I've avoided installing node on a Mac using the normal methods (mostly because of the permission issues with /usr/local), and instead switched to using NVM: https://github.com/creationix/nvm

It'll install node and npm into your home directory, and allow you to switch versions of node on the fly (similar to RVM for Ruby).

And I'd suggest uninstalling node/npm: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
