问题描述

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,它说执行 gem install rdiscount --platform=ruby 以确保它已正确安装.我收到以下错误:

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

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

ERROR:  Error installing rdiscount:

我已尝试此建议,并删除了重复的libiconv-2.dll 文件,但问题仍然存在.有什么建议吗?

推荐答案

此时RDiscount在Windows上坏了,见GitHub 上的第 74 期

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 来验证它是否正确编译:

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

希望对您有所帮助.
