尝试用Ruby加载win32/sound时出错

所以我一直在努力解决这个问题，但我对Ruby不够了解，无法完全理解这个问题

所以我想播放ruby脚本中的声音。因此，在安装Ruby 2.2.1之后，我安装了最新版本的gems，然后继续下载win32 sound加载项，如下所示

C:/Program Files/Ruby22-x64/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- ffi_c (LoadError)

gem安装win32 sound

安装完成后，我尝试使用以下代码从命令行运行一个简单的脚本

require 'win32/sound'
include Win32

Sound.play('chimes.wav')

然而，当我这样做的时候，我最终得到了如下错误

我有点困惑。我原以为我把所有东西都安装好了，但现在我不太确定
