Error when trying to install Karma

Question

When I try to install karma using the command

npm install -g karma

I am getting the following errors, which I can't decode. npm installed under my user account so permissions should not be an issue, nor does the error message indicate that it might be. I tried executing it with sudo just for the sake of it, and got the same message. Any ideas?

This seems like a duplicate of this SO question, where karma is actually installed but the karma-cli package needs to be installed globally as well using npm install -g karma-cli
