rvm - Homebrew 要求打破了 Yosemite 上的 rvm 要求

Question

在 iMac(2010 年中)和 Air(2010 年末)上更新为 Yosemite。我的开发者环境 [rvm 1.25.33, ruby​​ 2.1.2, homebrew] 在 iMac 上没有问题，但是当我尝试运行 rvm 要求时，Air 出现错误:

Checking requirements for osx.  
Installing requirements for osx.  
Updating system.....  
Installing required packages: gcc46, libyaml, readline, libksba....  
Error running 'requirements_osx_brew_libs_install gcc46 libyaml readline libksba',

+ case "$1" in  
+ [[ -t 1 ]]  
+ return 1  
+ printf %b 'There were package installation errors, make sure to read the log.  

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

+ case "$_system_version" in  
+ return 1  
Requirements installation failed with status: 1.

我可以手动安装所有这些文件，除了 gcc46，每次都会出错。是的，我安装了 CLT 6.1(几次)，但 Homebrew 软件似乎忽略了这一点，并坚持安装 gcc46 作为依赖项。

brew 更新和 brew doctor 说一切都很好。日志指出:

Installing gcc46 from homebrew/homebrew-versions  
Error: An unsatisfied requirement failed this build.  
gcc46: OS X Mavericks or older is required for stable.  
Use `brew install devel or --HEAD` for newer."

在 gcc49 已经可用的情况下 brew install --HEAD gcc46 似乎不合逻辑，但是经过两天的空研究和与此搏斗后，我尝试并得到:

No head is defined for gcc46

我已经重新安装了 Homebrew 和 rvm 四次，但每次都遇到相同的错误。如果不是因为我的 iMac 更新没有问题，我可能会把这归结为简单的不兼容。我的开发人员环境在两个系统上都是相同的。任何帮助将不胜感激!

您需要更新 rvm:

rvm get head

我即将推出下一个稳定版，所以明天就足够稳定了:

rvm get stable
