amazon-ec2 - 尝试使用橡胶部署 jRoR 应用程序并获得 NoMethodError : undefined method `authorize_port_range' for nil:NilClass

Question

这是我第一次使用橡胶或部署到 Amazon EC2。我正在关注这个 Railscast .我用谷歌搜索了一遍，似乎没有其他人遇到这个问题。这是我运行时的控制台日志 cap rubber:create_staging :

我的猜测是它正在寻找一个范围，并且在堆栈跟踪中您给出的范围是从一个端口到同一个端口和 ruby​​，尤其是 jruby 可能会错误地解释端口范围。

您可以尝试在 irb 上运行您的 jruby 版本
(22..22).to_a看看你得到了什么。在 mri 你会得到 [22]但是在 jruby 中可能存在实现错误。

我认为失败时正在执行的代码在这里:

又看了几分钟后，很明显，橡胶将参数传递给了雾 gem ，我很确定即使范围可能会解决，雾使用它的方式也需要一个范围。您可以尝试从 21 到 23 或 22 到 23 的范围，看看是否能让您克服错误。另外，请注意，您使用的橡胶版本远远落后于主版本。我没有任何引用来指定这是需要的还是不需要的，但您应该意识到这一点。祝你好运。
