Having some difficulty building a rails app titled Adventures. I’m supposed to be creating a customer controller with 2 actions called home & about. The root path should give me a "localhost:3000/(adventures, etc.). I also need to scaffold a few attributes such as state name and activity cost. Not able to get the adventure attribute info after scaffolding and setting up the info. I’ve attached the image I’ve been getting. 
The error indicates there is already a service running a port 3000, try a different port:
rails server -p 8000
Or figure out what is running on port 3000
