所以你好！主要的未定義方法`root'：對象

我想用紅寶石的軌道讓我的網站看起來不錯，並有良好的語言與紅寶石。我喜歡這款紅寶石，而且總是有。很好。

所以我的問題是，爲什麼我必須看到這個錯誤？

未定義的方法'根」主：對象

我得到這個，當我去我的網站，看看錯誤的PHUSION頁。這裏是長輸出：

Ruby on Rails應用程序無法啓動這些是可能的原因：應用程序代碼中可能存在語法錯誤。請檢查這些錯誤並修復它們。可能未安裝必需的庫。請安裝此應用程序需要的所有庫。應用程序可能未正確配置。請檢查所有配置文件是否寫入正確，修復任何不正確的配置，然後重新啓動此應用程序。應用程序依賴的服務（如數據庫服務器或Ferret搜索引擎服務器）可能尚未啓動。請啓動該服務。有關該錯誤的更多信息可能已寫入應用程序的日誌文件。請檢查它以分析問題。錯誤信息：主未定義的方法`根」：對象 Exception類： NoMethodError 應用根： /家庭/ $ USER/rails_apps /迷回溯：

任何人都知道這是爲什麼發生？

以下規格是：

寶石列表--local軌

*當地的寶石*

軌（2.3.14）

紅寶石-v & &寶石-v 紅寶石1.8.7（2011-02-18 patchlevel 334）[x86_64-linux] 1.8.23

在我的config/environment.rb中我指定了rails 2.3.14

建議會很好，有幫助。坦克全部！附：請原諒我的英語技能 - 他們不好。

另外，我使用cPanel，但沒有使用cPanel帳戶來查看和處理這個應用程序。

也許應用想讓您定義的config/routes.rb中的根路徑（詳情開放的config/routes.rb中）

我有這樣的：＃你可以有你的網站與map.root路由的根源 - 只記得刪除公共/ index.html的。 root：to =>「home＃index」＃查看所有路由如何使用「rake routes」＃安裝默認路由作爲最低優先級。＃注意：這些默認路由使每個控制器中的所有操作都可以通過GET請求訪問。如果您使用命名路線和資源，您應該考慮刪除或註釋掉它們。 map.connect'：controller /：action /：id'map.connect'：controller /：action /：id。：format'end – 2012-04-25 00:07:35

是的，如果你讀過它，寫上你應該設置'map.root' ;可能你刪除/重命名了public/index.html，這是由rails用來設置一個新項目的主頁，所以現在應用程序錯過了一個主頁;你應該指定主頁設置'map.root：controller =>「my_controller」'。說，我必須補充說你的config/routes.rb它比rails 2更類似於rails 2！ – mdesantis 2012-04-25 00:16:02

我應該怎樣做配置/路線。rb更像是導軌2？ – 2012-04-25 00:32:11

希望這有助於在這裏......我基本上是一個全新安裝。我做了一個腳手架電話：

[email protected]:~/workspace/workspace (master) $ rails g scaffold User userID:integer index name:string email:string password:string lastLogin:datetime

這顯然是錯誤的......但如何撤消它？由於我錯誤地完成了「rake db：migrate」，因此我們可以通過簡單的命令將其刪除。錯了，但幸運的是，在比較我的github後，我注意到我的routes.rb文件的開始有所不同。

resources :users

紅寶石支架銷燬命令已經離開，其中搞砸了整個事情的routes.rb文件中的一個小行。沒有差異比較github，我從來沒有注意到。下面是在人的情況下原來的錯誤是盲目Google上搜尋它像我是...
