我对 Rails 很陌生，正在尝试通过橡胶设置我的应用程序。我能够毫无问题地启动一个测试应用程序，但在实际尝试硫化我构建的应用程序时遇到了某种错误。试图搜索高低无济于事。任何人都知道我需要做什么才能摆脱这个问题？非常感激。

我们遇到了同样的问题：

rubber vulcanize complete_passenger_postgresql

这似乎是第 53 行的 Rubber/commands/vulcanize.rb 中的 gem 中的错误，因为它试图从一个非法的字符串中减去一个数组。我将其更改为（作为 sudo）：

invalid = (arg.kind_of?(String) ? [arg] : arg) - VulcanizeThor.valid_templates

这允许设置，但是我不确定硫化是否比预期的要多，因为我也是橡胶新手。这是一项严厉的措施，因此请先在非生产环境中尝试小心！
