There is another instance of webrick running of the port 3000. Use the command

ps aux | grep webrick

To verify it. And then kill it.

EDIT:

The ps command shows you a list of the current running programs of your machine. Each program on a unix-like machine comes with a PID number associated with it. In your case, the other running instance has a pid = 12288. So you can use:

kill 12288

To kill the other instance of the server.
