无法使用RVM安装Ruby
我在使用RVM安装Ruby时遇到了麻烦，这个让我很难过。 我正在运行OS Mavericks，使用最新的XCode和xcode命令行工具。 我（在我的知识）相同的设置在另一台机器上没有问题。
RVM似乎安装没有问题。
在尝试rvm install 2.1时，我收到以下错误消息：
ruby-2.1.1 - #removing src/ruby-2.1.1.. Searching for binary rubies, this might take some time. No binary rubies available for: osx/10.9/x86_64/ruby-2.1.1. Continuing with compilation.

Halting the installation. 我的第一个想法是运行RVM要求，这导致另一个错误消息

我按照这里的建议，现在花了几个小时在网上看，但还没有解决方案对我有用。 任何想法和想法都是最受欢迎的 – 这个让我难过。
一旦你有gcc46 insall你需要将它设置为默认编译器。 您可以在此处找到有关不同方法的信息： 在Mac OS X Leopard上将GCC 4.2设置为默认编译器
然后，如输出所示，使用brew tap --repair和brew doctor ，它可以为您提供更多信息。
