我知道有几个相关的帖子，我尝试了几种解决方案。
我已经审查并尝试过以下方面的消息：
Cannot install Puma gem on Ruby on Rails， puma在github上发布202， puma在github上发布424，和 hicknhack软件/导轨迪斯科/维基/安装，彪马在窗口 还有一些其他来源，我无法发布完整的链接，因为我没有代表。
我知道需要下载openssl并在gem install命令中引用它。我已经下载并尝试了各种版本的openssl，我使用的最后一个是来自http://indy.fulgan.com/SSL/的1040064 openssl-1.0.2a-i386-win32.zip
我正在跑步：
版本ruby = ruby 2.0.0p598（2014-11-13）[i386-mingw32]
rails版本= 4.1.8
Windows 7,64位
完全错误：
