在Windows 7 x64上安装Ruby和Rails以及DevKit的问题 – 需要修复
我在尝试安装ruby和rails时遇到了很多问题。 在清除以前安装的版本之后，我已经尝试了没有和现在。
当试图运行“gem install rdiscount –platform = ruby”时，我收到以下错误：

谢谢

似乎你在带有空格的目录中安装了Ruby（沿着DevKit？）。
如Ruby自己的安装程序所示，不推荐使用带空格的路径（这就是默认为C:\Ruby193
作为DevKit一部分的编译器GCC在使用空格的路径时遇到问题，因此建议将DevKit的安装放置在没有空格的路径中（例如C:\DevKit ）
所有这些都在RubyInstaller和DevKit安装说明页面中提到
我建议再次卸载和安装。 另外我建议使用http://railsinstaller.org/中的Rails安装程序，根据我的经验，这是在Windows机器上安装rails和ruby的最无痛的方法。
