使用RVM安装Ruby时出错（OSX 10.8）
当尝试使用RVM（rvm install ruby 1.9.3）安装Ruby 1.9.3时，我收到以下错误：
Searching for binary rubies, this might take some time. No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p362. Continuing with compilation.

你的主要问题是：
configure: error: C compiler cannot create executables
因此，寻找解决该问题的方法。 喜欢：
rvm install 1.9.3 --with-gcc=clang
其他例子：
- 如何在Mac OS X Lion中安装Ruby 1.9.3？
- 为什么我得到“C编译器无法创建可执行文件”（在此之前成功编写C代码并编译）？
Xcode->首选项
检查“命令行工具”
这是重复的，已经很少有答案，但我已经修复了RVM，确保先运行rvm get head并读取输出 – 修复程序显示在那里。
