【问题描述】：
env => Mac。操作系统优胜美地。
我有一个项目使用 ruby 2.1.3 。 但是当我捆绑安装时，有一个我无法修复的错误。 gem unf_ext 有问题
这是我的终端消息：
$ gem install unf_ext -v '0.0.6'
Building native extensions. This could take a while...
ERROR: Error installing unf_ext:

Gem files will remain installed in /Users/vincent/.rvm/gems/ruby-2.1.3/gems/unf_ext-0.0.6 for inspection.

我尝试 brew update 和 xcode select install 但仍然无法正常工作。 有什么建议吗？

非常感谢！与链接相同。我已经解决了这个问题，只需从 Apples Developer 下载页面重新安装适用于 OS X 10.10 的 Xcode 6.2 的 Command-Line-Tools commandlinetoolsosx10.10forxcode6.2.dmg。

很高兴它解决了您的问题。我也将其发布为答案。
