對於軌道3在Windows上安裝mysql2寶石，你可以參考一下安裝的具體步驟上 -

感謝您的回覆，我在發佈後不久發現了這個指南，這是讓它達到了目的，但它仍然失敗。 – 2011-05-03 09:43:14

在rorguide詳細對我也沒有工作的過程。我已經解決了將mysql社區服務器zip文件（win x86）中的libmysql.lib文件直接複製到gem的ext \ mysql2目錄中。這似乎使它正確地找到lib。 mysql2 gem的0.3.2版本似乎在查詢困難時掛起，但來自github（https://github.com/brianmario/mysql2）的master分支已修復它。

我最終建設爲直Ruby擴展：

subst X: "C:\Data\MySQL" 
gem install mysql2 --platform=ruby -- -with-mysql-dir=X: --with-mysql-lib=X:\lib --with-mysql-include=X:\include

我需要單獨的include指令，因爲我使用MySQL 5.5（和看起來像目錄結構已經改變後5.1）
