为什么不使用RVM安装Ruby 1.9.2-head?

标签: ruby rvm ruby-1.9

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?

我拥有rvm notes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:

rvm笔记也说

  

要安装Ruby 1.9.2,您需要安装并设置Ruby 1.8.7。

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

此解决方案已经过测试。

只要您通过RVM安装了另一个Ruby(可能是Ruby MRI 1.8),就不必拥有Ruby系统。

值得庆幸的是,Ruby 1.8不需要安装Ruby,因此您没有引导问题。
