我从http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-1.9.3-p448.exe将1.9.3 ruby 安装到 C:\Ruby193。
我将https://github.com/downloads/oneclick/rubyinstaller/DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe下载到 C:\ruby_dev_kit 并从那里运行 ruby dk.rb init 然后 ruby dk .rb 安装
全部安装成功。
然后，当我运行 gem install json 时，我一直在安装 json (1.4.6) 系统找不到指定的路径。
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing json (1.4.6), and Bundler cannot continue.
Make sure that `gem install json -v '1.4.6'` succeeds before bundling.
我也试过 gem install json --platform=ruby 没有改变任何东西。似乎存在 c 编译器问题，但我正确定义了路径并且也关联了 DevKit。尝试卸载和安装，没有帮助。有什么想法吗？
