尝试安装ruby和rails时遇到了一些问题。在清除以前安装的版本后,我已经尝试了两种方法,现在已经尝试过。
当尝试运行“gem install rdiscount --platform = ruby”时,我收到以下错误:
C:\Windows\system32>gem install rdiscount --platform=ruby
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing rdiscount:

我按照指示运行了DevKit安装,似乎工作正常。 Rails以前工作但现在不行。有人对如何使这个工作有任何建议吗?或者是卸载的情况并重新尝试?

我建议您再次卸载和安装。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的最无痛方法。

似乎你在一个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,不建议使用带空格的路径(这就是默认为C:\Ruby193
作为DevKit一部分的编译器GCC在使用空格路径方面存在问题,因此建议将DevKit的安装放置在无空格的路径中(例如C:\DevKit
)
所有这些都在RubyInstaller和DevKit installation instructions page
