You are attempting to start another servr at the same port as one which
is already running. You need to find and kill the one before you can
run another.

i have restarted my pc but i still have the same pb, i wasnt able to fins the process which was running,thanks

If you're running *NIX you can see which process is listening on port 3000 by running lsof -i :3000

You can also change the port you want your rails server to listen to with the -9 option.

For example : rails server -p 8080 will listen on port 8080.
