"npm install brickpi-raspberry" fails

I’m interested in scripting with node.js, so I followed the link from http://www.dexterindustries.com/BrickPi/program-it/ and tried following the directions on http://www.dexterindustries.com/BrickPi/program-it/node-js/. “sudo apt-get install nodejs npm” worked for me, but then this command:

npm install brickpi-raspberry


npm http GET https://registry.npmjs.org/brickpi-raspberry

How do I install this?
