我想通过rvm1-capistrano安装rvm。每次我运行任务时它都会告诉我Ruby [version] is not installed。这很奇怪，因为我已经知道它没有安装，这就是我正在运行任务的原因：安装它。这是为什么？
这是一种开箱即用的香草。我什么都没改变。我添加了以下内容：
设置：rvm_ruby_version，'2.0.0-p353'＃to deploy.rb，同样的错误没有/没有 set：pty，true＃deploy.rb 要求'rvm1 / capistrano3'＃to Capfile
根据其他人的推荐，我在我的应用的根目录中添加了.ruby-version，其中2.0.0为内容。
我不理解的是什么？为什么安装ruby的任务会告诉我ruby没有安装？
