Ruby on Rails的在Windows SQLite的問題7 64

當我嘗試做db:create在SQLite數據庫使用Windows 7這個數據庫配置的x64Ruby on Rails的在Windows SQLite的問題7 64

development: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    timeout: 5000

我得到這個，有點滑稽錯誤

你能否在你的db目錄下創建一個名爲development.sqlite3的空文件。運行rake db：遷移並告訴它是否有效？ – 2009-10-13 21:06:40

@AurélienBottazini：不會，同樣的錯誤 – 2009-10-15 08:32:14

通過在路徑中放入sqlite3.dll來修復。問題實際上是，Windows 7沒有向我顯示關於丟失DLL的錯誤。當我在Vista上嘗試過同樣的事情時，發現sqlite3.dll未找到。但我完全不知道，爲什麼這隻發生在Win7上
