Question

首先，我是Sass / Compass / Ruby的新手。

Ruby安装为2.0 - ruby 2.0.0p481（2014-05-08修订版45883）[universal.x86_64-darwin13]

其次，安装了XCode - 版本6.1.1（6A2008a）

第三，使用 Sass＆amp;指南针在行动的指示（2013年，Netherland等），我安装了Sass。

$sudo gem install sass -- it installed as version 3.4.9

然后，

$sudo gem install compass -- it results in several errors.

因此，在阅读了版本不兼容的情况后，我卸载了Sass并尝试使用以下方法重新安装Sass / Compass：

$sudo gem install compass

现在我得到以下内容，除了Sass没有安装之外，它与先前的一组错误消息相同：

我将非常感谢您的建议。

更新：01/02/2014

我安装了OS 10.10.1，更新了Xcode，然后重新安装了＆＃34; $ sudo gem install compass＆＃34;命令。 Sass＆amp;指南针安装没有故障。

安装在Mac上的Sass 3.4.9（10.9.5）;指南针不会安装; XCode已安装
