我一直在检查这里的其他问题，因为在使用RVM的Lion中安装ruby 1.9.3时出现问题，问题似乎与我的相同，所以我尝试了解决方案但没有成功：
我首先尝试过：
rvm install 1.9.3 --with-gcc=clang
返回：
Installing requirements for osx/10.7/x86_64, might require sudo password.
Skipping `brew update` make sure your formulas are up to date.

ruby-1.9.3-p392 is not installed.
To install do: 'rvm install ruby-1.9.3-p392'
注意ruby-1.9.3-p392 is not installed.在结尾附近的显示方式。
之后我尝试按照以下建议做了以下事情：
CC=/usr/bin/gcc-4.2 rvm install 1.9.3 --enable-shared
但它回来了：
You requested building with '/usr/bin/gcc-4.2' but it is not in your path.
所以我基本上被困在这里，不知道如何继续。任何帮助将受到高度赞赏。提前谢谢。

这应解决它：
rvm get head
rvm install 1.9.3 --autolibs=4

安装失败，因为Homebrew维护的某些软件包需要更新。在代码的第二行“跳过brew update，确保您的公式是最新的。”
brew update
可能需要
sudo brew update
然后
rvm install 1.9.3 --with-gcc=clang
应该覆盖rvm，允许您下载稳定版本的ruby 1.9.3
sudo rvm install 1.9.3 --with-gcc=clang
也可以。
