ruby-on-rails - 无法使用 RVM 安装 Ruby

Question

我在使用 RVM 安装 Ruby 时遇到了问题，这个让我很困惑。我在 OS Mavericks 上运行，使用最新的 XCode 和 xcode 命令行工具。我(据我所知)在另一台机器上进行了相同的设置，没有任何问题。

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.

我的第一个想法是运行 RVM 需求，这导致了另一个错误消息

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

我听从了这里的建议，现在已经花了几个小时在线查找，但还没有适合我的解决方案。任何想法和想法都是最受欢迎的——这个让我很困惑。

Answer 1

安装 gcc46 后，您需要将其设置为默认编译器。您可以在此处找到有关执行此操作的不同方法的信息:Setting GCC 4.2 as the default compiler on Mac OS X Leopard

然后如输出所示，使用 brew tap --repair 和 brew doctor 为您提供更多信息。
