Nodejs+socket.io cannot find module

i try to follow this tutorial (http://www.radiusdesk.com/getting_started/install_ubuntu_node.js) and i stuck on the nodejs step.

I installed nodejs but theres a problem with the socket.io module.

I used sudo npm -g install socket.io@0.9.x to install../usr/local/lib/node_modules/socket.io exists..

OS: Raspian (raspberrypi)
