It worked perfectly in Linux. I've just installed nodejs, nowjs, etc, runned this server script, but it keeps throwing this error.
Any ideas?

Answer
Nevermind. Facepalm. The node_modules folder I had was the same that I used/installed in Linux, so I believe that some parts were compiled specifically for Linux, or whatever.
Solved by erasing the node_modules folder and reinstalling.
I hope it helps to anyone with the same doubt!
