在OSX Yosemite（或Sierra）中安装指南针时出错 [英] Error installing compass in OSX Yosemite (or Sierra)

问题描述

美好的一天
我有一台装有OSX优胜美地的Mac
的Mac我试图用命令安装指南针：

 sudo gem install compass 

但我收到以下错误：

 
构建本地扩展。这可能需要一段时间... 
错误：安装指南针时出错：
错误：无法构建gem原生扩展。 
 
 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby -r ./siteconf20151001-1122-1jqcu8r.rb extconf.rb 
 mkmf.rb can在/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h 
 
 extconf失败时找到ruby的头文件，退出代码1 
 
 Gem文件将保留安装在/Library/Ruby/Gems/2.0.0/gems/ffi-1.9.10进行检查。 
结果记录到/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，我使用命令更新了gem


sudo gem update - - 系统

并且发生更新没有错误

解决方案您可能需要先安装命令行开发工具。

  xcode-select --install 
  

然后再次尝试 sudo gem install compass

Good day I have a Mac with OSX Yosemite I'm trying to install the compass with the command:

sudo gem install compass

but I am getting the following error:

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

before attempting to install the package I updated the gem with the command

sudo gem update --system

and the update occurred without errors

解决方案

You probably need to install the command line developer tools first.

xcode-select --install

Then try sudo gem install compass again
