用橡胶将JRuby on Rails部署到AWS EC2

Question

我正在尝试使用橡胶将一个基本的JRuby on Rails应用程序部署到EC2。我遵循这指南，唯一的区别是我使用的是JRuby。

这个是可能的吗？我可以在complete_passenger_postgresql中使用所提供的模板之一(例如JRuby )吗？

我看到橡胶-ruby.yml文件中有一行可以指定ruby_version。是否需要指定要使用JRuby？

是否有不同的模板需要我使用？

现在，当我尝试命令'cap rubber:create_staging‘时，我得到了以下错误

jruby-9.0.0.0.pre1是一个预发布版，因为还有另一个pre2，请尝试一下，如果这不能解决，您应该在报告问题之前先检查一下最新的jruby-1.7.x是否有效。
