Check if you had another instance of ionic serve already running on your computer, it seems like the port number was already in use, most likely by a previous instance of ionic serve.

If you are still getting this error when no other ionic serve instance is running, try after restarting your computer. Maybe the new cli is not completely closing a running ionic serve instance.
