我在尝试在我的 Windows 7 机器上设置 RoR 时遇到了一些错误。我使用 RubyInstaller 和 DevKit 安装了 Ruby。在他们的指示中，它说要执行gem install rdiscount --platform=ruby以确保正确安装。我收到以下错误：

C:\Windows\system32>cd ../../DevKit

C:\DevKit>gem install rdiscount --platform=ruby

ERROR:  Error installing rdiscount:

我已经尝试过这个建议，并删除了一个重复的libiconv-2.dll文件，但问题仍然存在。有什么建议么？

此时，RDiscount 在 Windows 上已损坏，请参阅GitHub 上的问题 #74

如果您已经安装了 Ruby 和 DevKit，那么您可以安装其他 gem，例如json或RedCloth验证它是否正确编译：

gem install json --platform=ruby
gem install RedCloth --platform=ruby

希望有帮助。
