Ruby on Rails的4.2.2引發ArgumentError（錯誤的參數數目（2 1））

Question

我最近清理了我所有的寶石，由於這個問題，並試圖通過以下重新安裝：

$ gem install rails 
$ rails new myproject 
$ cd myproject 
$ rails server 

雖然上面看起來非常簡單的一個新的軌道安裝中，我得到了以下500錯誤：

$ rails server 
=> Booting WEBrick 
=> Rails 4.2.2 application starting in development on http://localhost:3000 
=> Run 'rails server -h' for more startup option' 
=> Ctrl-C to shutdown server

什麼AM-我失蹤？

日誌中提到機架的版本1.6.3。嘗試將gem 'rack', '1.6.2'添加到您的Gemfile並從命令行運行bundle update rack。重新啓動您的服務器。目前看來，這似乎奏效。
