Some of these answers were difficult to understand for me, so I'm going to write the answer that would've helped me.

node is something like a radio telemetry solving program, they just happened to snag the name node first. nodejs is what you're after. So make sure you:

apt-get install nodejs

then, to fix the lame naming issue, create a symlink. A symbolic link between node and nodejs.

sudo ln -s /usr/bin/nodejs /usr/bin/node

The first part is the original file placement, and then where it should link to. You could also create an alias in your bash profile, which is also pretty easy.
