试图在Windows 8上安装mysql2 gem与Ruby 2

Question

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

我尝试使用下面的命令来安装mysql2宝石（从Windows PowerShell中）：

gem install mysql2 

这里就是我得到：

你可以参考Ruby on Rails installation issue (Windows)获得解决方案。

注意：对于64位窗口，应该使用64位连接器。
