使用Rvm安装Ruby 1.9.3时出现问题

我正在尝试使用本指南安装ruby 1.9.3： http ： //www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/ 。

当我运行rvm install 1.9.3我收到此错误

 Searching for binary rubies, this might take some time. No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p392. Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies. Installing requirements for osx, might require sudo password. Skipping `brew update` make sure your formulas are up to date. Cowardly refusing to continue, please read 'rvm autolibs'. 

然后我运行brew update ，我明白了

 Already up-to-date. 

我也试过跑brew doctor ，我明白了

 Your system is raring to brew. 

怎么了？ 我该如何解决？？

Answer 1

我有同样的问题，这对我有用：

 \curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enabled 

资源：

https://rvm.io/

Answer 2

尝试：

 rvm list known 

如果没有返回任何内容，或者不包含您正在寻找的ruby版本尝试更新

 rvm get stable 

然后尝试再次安装所需的ruby版本。
