我正在尝试使用以下步骤在我的 Mac OS X 10.8 上安装 Ruby 2.0 http://www.interworks.com/blogs/ckaukis/2013/03/05/installing-ruby-200-rvm-and-homebrew-mac -os-x-108-山狮
所有步骤都成功完成，直到最后。我跑之后
rvm install 2.0.0
它给了我以下输出：
/Users/aaron/.rvm/src/ruby-2.0.0-p0 has already been removed.
/Users/aaron/.rvm/rubies/ruby-2.0.0-p0 has already been removed.
Searching for binary rubies, this might take some time. No binary
rubies available for: osx/10.8/x86_64/ruby-2.0.0-p0. Continuing with
compilation. Please read 'rvm mount' to get more information on binary
rubies. Installing requirements for osx, might require sudo password.

看起来它无法提取源。有什么建议可以让我正常工作吗？提前致谢。
