RoR 错误：无法将 Warbler::WebxmlOpenStruct 转换为数组

Question

我安装了 Warbler gem 来创建 .war 文件。我尝试使用 warble 命令创建 .war 文件，但每次尝试时都会收到以下错误：

warble aborted!
can't convert Warbler::WebxmlOpenStruct to Array (Warbler::WebxmlOpenStruct#to_a
 gives Warbler::WebxmlOpenStruct)

如何解决它？

Answer 1

我还没有用 1.9.2 测试过 Warbler，我猜这是一个错误。我建议使用 JRuby 来运行它以获得最佳结果，直到问题得到解决。您介意将其提交到 https://github.com/nicksieger/warbler/issues 吗？包含 config/warble.rb 的内容（如果有）。谢谢！
