我已经在我的 Mac 上安装了 coreAudio，我想启动 outloop_sine.rb 示例：

ruby outloop_sine.rb

然后返回：

/usr/local/Cellar/ruby/2.1.1/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require': dlopen(/usr/local/Cellar/ruby/2.1.1/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-13/2.1.0/narray-0.6.0.9/narray.bundle, 9): Library not loaded: /usr/local/opt/ruby/lib/libruby.2.1.0.dylib (LoadError)

    from outloop_sine.rb:1:in `<main>'

然后我安装所需的 narray：

sudo gem install narray

那工作，但是当我再次启动 outloop_sine.rb 示例时，会出现相同的错误...

您的帮助：

ruby --version

ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]

和：

ls -l /usr/local/Cellar/ruby/2.1.1/lib/ruby/gems/2.1.0/extensions/x86_64-darwin-13/2.1.0/narray-0.6.0.9/

total 536

-rw-r--r--  1 root  admin    5546  9 aoû 00:04 nmatrix.rb

最后，我没有 libruby：

ls /usr/local/opt/ruby/lib/

ls: /usr/local/opt/ruby/lib/: No such file or directory

第一条错误消息需要：

Library not loaded: /usr/local/opt/ruby/lib/libruby.2.1.0.dylib (LoadError)

我的 coreAudio gem 有什么问题？
