安装错误 - 在Windows 7上安装MySQL2 Gems

Question

我无法为我的rails应用程序安装最新版本的mysql2 gem。我已经尝试了建议in this answer的选项。但是安装的旧版本没有任何错误！     gem卸载mysql2     gem install mysql2 -v 0.2.6

以下是我尝试安装最新版本的mysql2 gem时弹出的错误

C:\Users\EcoAd>gem install mysql2 -v '0.3.16' -- '--with-mysql-lib="C:\Program Files\MySQL\MySQL Server 5.6\lib" --with-mysql-include="C:\Program Files\MySQL\MySQL Server 5.6\include"'

Temporarily enhancing PATH to include DevKit...

This could take a while...
