所以我想我的配置3.0.9軌道應用程式使用HTTPS和SSL通過添加以下行到我的環境配置搞砸了我的軌道依賴關係：
config.middleware.insert_before ActionDispatch::Static, "Rack::SSL"
和定義機架:: SSL依賴在我的Gemfile
gem 'rack-ssl', :require => 'rack/ssl'
出於某種原因，沒有工作，所以我試圖通過撤消上述第一回滾寶石依賴，然後
gem cleanup
未如此工作，我做了以下愚蠢的事情：
gem uninstall rack-ssl
和
gem uninstall railties
其卸載都railties 3.0.9和3.1.0。
顯然我沒有前進的道路上一些不好的事情，但現在我不能運行軌道，我得到以下錯誤：

誰能幫助我？我試着卸載並重新安裝rails gem，但沒有任何工作。
編輯：我意識到，切換到系統版本的紅寶石（從我的RVM默認）解決了這一問題，所以我卸載，然後重新安裝RVM，紅寶石，Rails和我所有的寶石。這並沒有完全解決這個問題，但我決定快速瀏覽一下我的Gemfile.lock，注意到rack-ssl仍然在那裏。刪除那個伎倆。
恢復你嘗試'束install'？ – molf
是的。當我回到以前的github版本時，我認爲它與應用程序本身沒有任何關係。 – mattangriffel
