Question

我正在尝试在我的macbook上安装断点但它无法编译。完整输出如下。我是Mac的新手，我不确定我可能做错了什么。我的Windows工作站今晚没有问题。

谢谢！

Apple最近推动了对Xcode（Xcode 5.1）的重大改变，如果您使用计算机附带的Ruby版本，将无法安装任何需要本机扩展的Ruby gem。虽然Breakpoint不需要任何，但Compass需要JSON gem，它可以。

有一个Compass Issue可以跟踪取消对JSON gem的直接依赖的进度，而只需要multi_json。

在与此问题完全相同的Breakpoint Issue中，我会详细描述正在发生的事情，并提供有关如何解决问题的选项。
