Не удалось запустить Rails Server после обновления до Rails 4

Question

Я только что обновился до рельсов 4, и когда я запустил рельсы s, я получаю вывод, вставленный ниже. Я убедился, что мои драгоценные камни обновлены, запустив bundle install и bundle update, и я проконсультировался с другими страницами SO с теми же проблемами, но не могу понять, что не так с моим. Пожалуйста помоги!

=> Booting WEBrick 
=> Rails 4.0.1 application starting in development on http://0.0.0.0:3000 
=> Run `rails server -h` for more startup options 
=> Ctrl-C to shutdown server

Может быть, есть ошибка в вашем config.ru файл.

Для Rails 3:

# This file is used by Rack-based servers to start the application. 

require ::File.expand_path('../config/environment', __FILE__) 
run YouApp::Application 

Для Rails 4:

# This file is used by Rack-based servers to start the application. 

require ::File.expand_path('../config/environment', __FILE__) 
run Rails.application
