我正在使用红宝石 2.0.0p576 (2014-09-19) [i386-mingw32]DevKit-mingw64-32-4.7.2-20130224
I'm using ruby 2.0.0p576 (2014-09-19) [i386-mingw32] DevKit-mingw64-32-4.7.2-20130224
我能够成功运行安装(必须安装 ssl 标头才能使其工作)，但是当我尝试部署 puma 服务器时，我不断收到此错误.我对 ruby 开发还很陌生，所以我不确定我可以研究哪些其他的东西，或者如何解决 gem 中的 EBADF 错误.
I was able to successfully run install (had to install the ssl headers to get it to work), but I keep getting this error when I try to deploy the puma server. I'm pretty new to ruby development, so I'm unsure what other things I could look into or how to resolve the EBADF error in a gem.
谢谢！
