Regarding the comment above where the error below is displayed:

`start_tcp_server': no acceptor (RuntimeError)

This appears when you are trying to bind to an already bound port. Trying a different port number should resolve.

did you run it via ruby -rubygems hi.rb (assuming this code is in hi.rb). If so, you don't need run App. Unless you are running it through another framework built on/with Sinatra.

Also might want to include haml...

You have a config.ru:

# config.ru
require 'my_app'
run MyApp

and a my_app.rb:

# my_app.rb
require 'sinatra/base'
require 'haml'

class MyApp < Sinatra::Base

get('/') { haml '%h1 Test' }

  # start the server if ruby file executed directly
  run! if app_file == $0
end

then in the folder where the my_app.rb is run this to start the app on localhost:4657:

rackup -p 4567
