在Windows上的Mysql本机扩展问题在ruby on rails gem time

Question

因为我刚接触ruby on rails，需要专业人士的帮助，在第一个应用程序安装中，因为我在我的系统上使用Mysql DB，我也安装了它的gem，但是当我做一个新的Bundle安装时我得到了这个错误项目应用。 当 bundle install处于以下阶段时， 会发生以下错误 ：

mysql2 0.2.13发布时没有Windows的二进制文件。 因此，需要编译。

由于您使用的是RailsInstaller，因此您已经拥有了解决此问题的所有组件，但我建议您阅读我发布的关于在Windows上编译mysql / mysql2 gem的博客文章：

http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/

然后，你可以bundle install ，因为已经安装了gem，它应该在之后工作。
