Question

我安装了ruby版本2.0.0.0p195（2013-05-14）[x64-mingw32]以及ruby gem版本2.0.3。我刚刚安装了MySQL社区服务器5.6.12（32位）安装程序。我试图让mysql或mysql2 gem工作，然后安装服务器以了解有关Ruby on Rails的更多信息。

当安装mysql2 gem我在下面得到这个错误时，任何人都可以指出我正确的方向来安装mysql2 gem所以我可以使用mysql在rails上使用ruby然后最终使用web serer。

我找到答案（对我来说）使用rails安装程序并卸载我的旧ruby信息。 Rails安装程序包括ruby，rails和sqllite3。同样，我安装了运行localhost：3000的WEBrick。它允许我拥有WAMP和Ruby / WEBrick。这并不理想，因为一切都没有在一个区域上运行，但是对于我需要的东西来说是非常好的，这是我想要使用HTML5和/或Rails（媒体应用程序）开发的一个副项目。
