試圖在Windows 8上安裝mysql2 gem與Ruby 2

Question

操作系統：Windows 8.1 Ruby版本：ruby 2.0.0p353（2013-11-22）[x64-mingw32] MySQL/Apache：AMPPS以及MySQL和Apache都是運行

我嘗試使用下面的命令來安裝mysql2寶石（從Windows PowerShell中）：

gem install mysql2 

這裏就是我得到：

你可以參考Ruby on Rails installation issue (Windows)獲得解決方案。

注意：對於64位窗口，應該使用64位連接器。
