錯誤：無法在Windows上構建gem本機擴展

Question

我在安裝' redcarpet '寶石時遇到以下錯誤。 它雖然在我的朋友機器上安裝沒有問題。 （我想安裝它來運行yard ）Ruby版本：1.9.3

cmd輸出：

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

更新：使用https://github.com/oneclick/rubyinstaller/wiki/Development-Kit提供的devkit安裝說明當我用json gem測試安裝時它也失敗了:(

我在github Native gem extension Error中經歷了排除故障的鏈接，並按照說明解決，但問題依然存在..

我添加了兩個路徑到Env var C:\\\\ruby_devkit\\\\bin;C:\\\\ruby_devkit\\\\mingw\\\\bin; 這將刪除Temporarily enhancing PATH to include DevKit...的行， Temporarily enhancing PATH to include DevKit...出現在cmd上的Temporarily enhancing PATH to include DevKit...

Answer 1

經過大量研究后，我發現罪魁禍首是RubyGems版本與原生擴展寶石的不兼容性！

我有ruby gems ver 2.4.1，但似乎> 2.4.0有這些問題

gem update --system 2.3.0為我做了訣竅:)

Answer 2

降級紅寶石寶石並不適合我。

工作是什么（安裝了最新版本的ruby gems）：

以管理員身份打開CMD並...

gem install json --platform=ruby --verbose
