ruby - 在 OSX Yosemite(或 Sierra)中安装 compass 时出错

Question

美好的一天我有一台装有 OSX Yosemite 的 Mac我正在尝试使用以下命令安装 compass :

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.rbmkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.hextconf failed, exit code 1Gem 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

更新没有错误

您可能需要先安装命令行开发人员工具。

xcode-select --install

然后再次尝试 sudo gem install compass
