我的config / routes.rb被调用两次。当我做rake路线时导致错误。应用程序也没有初始化。我试图从Rails 3.2.13升级到Rails 4.1.7。以下是我的config / routes.rb文件中的代码：
Rails.application.routes.draw do
puts "hello world!"
puts caller
root to: "home#index"
end
输出 rake routes 命令：
hello world!

You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:
