使用自制mac错误安装msgpack (0.5.8)

Question

我一直试图使用自制安装msgpack，它多次抛出以下错误：

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.

寻求解决这一问题的办法毫无成果。我的Ruby版本是2.4.1，但我不确定它是否是版本问题。

我在Github中的msgpack存储库中发现了这个问题：

https://github.com/msgpack/msgpack-ruby/issues/120

看起来这个问题在1.0.0版本中已经解决了。

您真的需要使用0.5.8版本吗？是否有可能更新创业板版本？
