Ruby on rails 更新到Rails 4后无法启动Rails服务器

我刚刚升级到rails 4，当我运行rails s时，我会将输出粘贴到下面。我已经通过运行

bundle install

和

bundle update

确保了我的gems是最新的，并且我已经查阅了其他SO页面，这些页面都有相同的问题，但我无法找出我的gems出了什么问题。请帮忙

您的config.ru文件中可能有错误

对于Rails 3：

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

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

对于Rails 4：

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

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