Rails 3 - 移動到/啓動生產服務器 - 生產數據庫未配置？

Question

我正在尋找部署我的第一個rails應用程序，並且遇到了一些問題。首先，開發服務器中的一切正常，所以我覺得我很好走。在將應用程序部署到我的主機失敗後，我嘗試第一次以生產模式啓動服務器，並收到了一些錯誤。

出於好奇，我創建了一個新的應用程序，完全新鮮，沒有我編輯任何代碼。我得到幾乎與我的數據庫相同的錯誤：

有沒有人在嘗試啓動生產服務器時遇到此問題？該database.yml的，只是良好的措施，是sqlite3的下列默認：

production: 
    adapter: sqlite3 
    database: db/production.sqlite3 
    pool: 5 
    timeout: 5000 

我覈實.yml沒有標籤（不，它應該自動生成）。

無論如何，我很感激幫助。

你安裝了sqlite3的寶石嗎？聽起來像它找不到適配器。
