使用自制的Mac OSX错误

Question

我一直在尝试使用自制安装msgpack安装msgpack（0.5.8），并多次引发以下错误：

Building native extensions. This could take a while... 
ERROR: Error installing msgpack: 
ERROR: Failed to build gem native extension.

/usr/local/lib/ruby/gems/2.4.0/gems/msgpack-0.5.8 for inspection. 
Results logged to /usr/local/lib/ruby/gems/2.4.0/extensions/x86_64-darwin-

搜索解决这个一直徒劳。我的Ruby版本是2.4.1，但我不确定它是否是版本问题。这是我第一次在Ruby上工作，所以任何帮助和耐心，将不胜感激！

谢谢

我发现msgpack库这个问题在Github上：
https://github.com/msgpack/msgpack-ruby/issues/120

貌似这个问题在1.0.0版本得到解决。
你真的需要使用版本0.5.8吗？是否有可能更新宝石版本？
