在约塞米蒂安装Ruby时出错

Question

我最近更新了我的OS到10.10，从那时起面临着通过RVM安装ruby的问题。有一个依赖于gcc46，我无法解决。任何帮助都是非常感谢的。下面是错误堆栈。

rvm reinstall ruby-1.9.3-p547

Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

编辑:

我能够使用下面的命令进行安装。

rvm install 1.9.3 --with-gcc=clang

有人能帮我理解一下上面的命令有什么区别吗？谢谢

谢谢@JanStrnádek的回答。我从左到右解决了所有的依赖关系，并使用下面的命令安装了gcc，并再次尝试安装ruby。啊，真灵。

brew install homebrew/versions/gcc48

尽可能使用最新版本，否则检查每个组件的正确版本，这些版本与您正在安装的组件的版本兼容。

如果您遵循本指南，这将容易得多。
