ruby-on-rails - 在 Windows 7 x64 上安装 Ruby and Rails 和 DevKit 时出现问题 - 需要修复

Question

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，我已经尝试过没有和现在。

尝试运行“gem install rdiscount --platform=ruby”时出现以下错误:

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:
    ERROR: Failed to build gem native extension.

我已经按照指示运行了 DevKit 安装，它似乎可以正常工作。 Rails 以前可以工作，但现在不行了。有人对如何使这项工作有任何建议吗？还是卸载重试？

谢谢

我建议卸载并重新安装。我还建议使用 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​​ 的最轻松的方式。
