为什么在Windows 8上安装json 1.8.6 gem不起作用？

我已经克隆了一个Rails应用程序，并试图在我的电脑上安装所有的gem。 我正在运行Windows 8.1 x64，并且已经在C：/ devkit上安装了x64 devkit，并且正在使用uru来pipe理ruby版本，以便我可以使用ruby 2.3.1。

当我运行bundle install或gem install json -v'1.8.6'-r –source http://rubygems.org/时 ，我得到以下错误日志：

我试过了：

• 安装json_pure并将其指定到我的gemfile中，以用于：mswin＆：mingw
• 运行软件包更新
• 用我的PATHvariables中的空格删除所有内容
• 在这里通过devkit故障排除选项的列表

我也浏览了很多类似的SE问题，但是与我的情况最相关的问题仍然没有答案。

还有什么可能会出错的build议？
