在 OSX Yosemite（或 Sierra）中安装指南针时出错

Question

美好的一天我有一个 Mac 和 OSX Yosemite 我正在尝试使用以下命令安装指南针：

sudo gem install compass

但我收到以下错误：

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

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby -r ./siteconf20151001-1122-1jqcu8r.rb extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.10 for inspection.
Results logged to /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-14/2.0.0/ffi-1.9.10/gem_make.out

在尝试安装包之前，我用命令

更新了gem

sudo gem update --system

并且更新无误

您可能需要先安装命令行开发人员工具。

xcode-select --install

然后再试一次sudo gem install compass
