Answer 1

Your site.js tries to listen twice on that port or something (another process) is already listening on port 3000. Find the service and stop/kill it. This command should help: lsof -i | grep 3000

Answer 2

Try running killall node, then node site.js again. If that doesn't work, at least you can rule out Node from the cause of this.
