I fixed my environment by doing the following:

sudo rm -rf /usr/local/lib/node_modules/*
npm install -g karma

And install any other global node modules you require without sudo

[verlok]

Same issue to me
Didn't solve using the solution @deepwell suggested :(

[MaerF0x0]

if sudo rm -rf /usr/local/lib/node_modules/* leaves you without npm ,you can get again by reinstalling node.

I also had to sudo chmod a+w /usr/local/lib/node_modules to get karma to install

I believe this issue has been addressed by the resolution to #6043, which is included in the latest stable version of npm, npm@2.0.0. Please upgrade npm and this problem should go away. Thanks for your patience!
