Node.js won't run files anymore in Mac Terminal

I installed Node.js and npm a few days ago to make a Turntable.fm bot with and it was compiling my code wonderfully. Today, I went to compile code and it would not work. It will recognize code errors, but it won't actually run my code. The only event that I can think of that has altered my Mac at all is installing Git (to install Github) last night. Has anyone experienced this problem or can help me? Thank you.

There is no error message, the command just never executes. It's almost as if it's stuck in a loop of sorts with no output at all.
