我一直在尝试使用RVM安装
Ruby 1.9.2-head,但一直收到此错误消息：
echo executable host ruby is required
为了通过RVM安装Ruby,是否必须拥有系统Ruby？
我有rvm笔记中给出的所有依赖项,但我没有安装任何系统Ruby.错误日志显示：

解决方法
rvm笔记也说
To install Ruby 1.9.2 you need to have Ruby 1.8.7 installed and set.
因此,安装Ruby 1.8.7,将其加载到环境并安装ruby 1.9.2
rvm install ruby-1.8.7-head rvm use ruby-1.8.7-head rvm install ruby-1.9.2-head
该解决方案已经过测试.
