It looks like you're running another app on the same port (localhost:3000). You can only run one app per port, so you'll have to shut down the server for the other app.

14,330 PointsThis discussion is a bit old now, but I ran into the same problem today, seemingly out of the blue.
In the OSX console:
lsof -i tcp:3000
Find the port ID (PID) under the resulting listing, then:
kill -9 <PID>
Where PID is the port ID you obtained from running the "lsof" command above. Worked like a charm. Not sure if this syntax would work for Linux or Windows consoles.
I found this solution from Stackoverflow: http://stackoverflow.com/questions/3855127/find-and-kill-process-locking-port-3000-on-mac
