我正在做Michael Hartl的rails screencast教程，並且在第7章中，我試圖將用戶添加到數據庫中，原因是測試用戶顯示頁面。當我創建一個用戶時，它會回滾一個SQLite3 :: CorruptException：數據庫磁盤映像格式錯誤錯誤。研究這個錯誤建議停止「後綴」過程，但我沒有安裝postfix。有任何想法嗎？請注意，我是新手，這很可能是我的一個簡單的錯誤！謝謝！從軌道控制檯獲取「SQLite3 :: CorruptException：數據庫磁盤映像格式不正確」

謝謝，這是訣竅！不幸的是，我無法贊成你，因爲我的聲望不夠高 – dax 2013-03-14 19:07:57
如果你正在瀏覽rails教程，你可能需要運行：rake db：populate – Techbrunch 2014-05-11 17:21:00
請小心，這個過程刪除並創建新的你的數據庫，所有的數據會有失落。 – 2017-03-10 21:34:47
