尝试使用 Ruby 2 在 Windows 8 上安装 mysql2 gem

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 都在运行

我正在尝试使用以下命令（来自 Windows powershell）安装 mysql2 gem：

gem install mysql2

这是我得到的：

您可以参考Ruby on Rails installation issue (Windows)获取解决方案。

注意：对于 64 位 Windows，您应该使用 64 位连接器。
