在Yosemite中安装Ruby时出错
我最近将我的OS X更新到10.10，然后面临通过RVM安装ruby的问题。 gcc46存在依赖性，我无法解决。 任何帮助表示赞赏。 下面是错误堆栈。

我能够使用以下命令安装。
rvm install 1.9.3 --with-gcc=clang
有人能帮助我理解上述命令的区别吗？ 谢谢
谢谢@JanStrnádek的答案。 我解决了从左到右的所有依赖关系并使用以下命令安装了gcc并尝试再次安装ruby。 有效。
brew install homebrew/versions/gcc48
请尽可能尝试使用最新版本，或者检查与要安装的组件版本兼容的每个组件的正确版本。
如果您按照本指南操作 ，将会更容易。
我对ruby来说是全新的，但是使用它对我来说很好。
