Error installing karma on Windows 7 - node.js

I'm trying to install karma using
npm install -g karma
but, even as the admin, I'm getting these errors:

Anyone have any ideas why this is happening? I have no problem running this on OS X Mountain Lion.

Answer 1

I ended up uninstalling node. Then used chocolatey to install it. That gave me a couple of errors but as I debugged, it turned out that for some reason, the npm config file had the wrong registry address to look up the packages. So when I executed
npm install -g karma
it would try to connect to the registry and couldn't. After fixing the address, everything worked smoothly. I was starting to question if my previously installed programs had changed any system config files or network settings. Evidently, there was no proxy issue encountered.
