Ruby on rails 无法使用RVM安装Ruby

我在用RVM安装Ruby时遇到了问题，而这一个让我很为难。我使用最新的XCode和XCode命令行工具在OS Mavericks上运行。据我所知，我在另一台机器上安装了相同的装置，没有任何问题

RVM的安装似乎没有问题

在尝试rvm安装2.1时，我收到以下错误消息：

我听从了这里的建议，现在花了几个小时上网，但还没有一个解决方案对我有效。任何想法和想法都是最受欢迎的——这一点让我感到困惑

一旦拥有gcc46 insall，您就需要将其设置为默认编译器。您可以在此处找到有关不同方法的信息：

然后，如输出所示，使用

brew点击--repair

和

brew doctor

，这将为您提供更多信息。

谢谢。我对永久更改默认值犹豫不决，但以下命令对我有效：

sudo rvm install 2.1--with gcc=gcc-4.2
