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。
rvm reinstall ruby-1.9.3-p547
ruby-1.9.3-p547 - #removing src/ruby-1.9.3-p547 - please wait
ruby-1.9.3-p547 - #removing rubies/ruby-1.9.3-p547 - please wait
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-1.9.3-p547.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

gcc46: OS X Mavericks or older is required for stable.
Use `brew install devel or --HEAD` for newer.

编辑：
我可以使用以下命令安装。
rvm install 1.9.3 --with-gcc=clang
有人可以帮我理解上述命令的区别吗？感谢

感谢@JanStrnádek的回答。我从左到右解决了所有依赖项，并使用下面的命令安装了gcc，并尝试再次安装ruby。它奏效了。
brew install homebrew/versions/gcc48
