尝试重新安装gem'eventmachine'
$ gem uninstall eventmachine
然后
$ bundle install ( in the same folder with your Gemfile)
或只是
$ gem install eventmachine ( if you are not using the Gemfile)

有人在评论中回答......见下文。
基本上虽然我有单独的Ruby版本,但由于某些宝石只安装在某些版本的ruby上,所以它变得令人困惑。
修复完全卸载了ruby和rails,然后重新安装。修好了!

在将ruby从1.9.3升级到2.4后,我在Windows上遇到了同样的错误。 我尝试了我发现的每一个修复,但最终唯一有帮助的是(不是那么明显,因此很难找到)重新安装新的 Ruby 再次 32位而不是64 。
我还用
安装了Eventmachinegem install eventmachine --platform=ruby
强制进行本机编译,因为我总是遇到msgpack问题,可以像这样解决(没有尝试使用默认的x86-mingw32
)
