ruby - 错误 : Failed to build gem native extension on Windows

Question

我在安装“redcarpet”gem 时遇到以下错误。它在我 friend 的机器上安装没有问题。 (我想安装它来运行 yard) ruby 版本:1.9.3

命令输出:

D:\Learning\Common_POM_FW\SampleProjects>yard
[error]: Missing 'redcarpet' gem for Markdown formatting. Install it with `gem install redcarpet`

D:\Learning\Common_POM_FW\SampleProjects>gem install redcarpet

更新: 使用 https://github.com/oneclick/rubyinstaller/wiki/Development-Kit 中提供的 devkit 安装说明当我用 json gem 测试安装时，它也失败了:(

我浏览了 github 中的故障排除链接 Native gem extension Error按照提示解决，问题依旧。。

我将这两个路径添加到 Env var C:\\ruby_devkit\\bin;C:\\ruby_devkit\\mingw\\bin; 这会删除行 Temporarily enhanced PATH to包括 DevKit... 出现在 cmd 上

Answer 1

最后，经过大量研究，我发现罪魁祸首是 RubyGems 版本与 native 扩展 gems 不兼容!!!

我有 ruby​​ gems ver 2.4.1 但似乎 >2.4.0 有这些问题

gem update --system 2.3.0 对我有用:)
