我正在尝试通过bundle在Windows 8（使用Ruby 1.9.3和RubyInstaller）上安装gem EventMachine，但是我收到以下错误。此处发布的所有先前解决方案均不适合我。我非常感谢提前任何帮助

答案 0 :(得分：2)
你可以写你的Gemfile：
gem 'eventmachine', '~> 1.0.0.beta.4.1'
再次运行bundle install，如果你有一些关于你正在请求另一个eventmachine版本的错误，并且当前有一个bundle of eventmachine，你可以删除“Gemfile.lock”并再次运行bundle install（尽管这样做并不好，但它对我有用）
PD：我希望这个解决方案也适合你。答案 1 :(得分：1)
确认上述答案有效。
首先，我强制它使用以下命令下载最新的eventmachine：
gem install eventmachine --pre
我将以下行添加到我的gemfile中：
gem 'eventmachine', '1.0.0', :platforms => [:mswin, :mingw]
然后使用以下行找到并编辑了我的gemfile.lock：
rake (10.1.0) #
## eventmachine (1.0.0)
eventmachine (1.0.0-x86-mingw32)
然后重新捆绑安装，一切都很顺利。希望这能帮到你！
