Spree Rails 应用程序启动错误 'Instance method "open" is already defined in Object'

Question

在生产环境中尝试运行我的 Rails 应用程序而不是开发时会发生此错误：

Instance method "open" is already defined in Object, use generic helper instead or set StateMachines::Machine.ignore_method_conflicts = true.

我是 Rails 的新手，需要一些帮助来解决这个问题。可能导致错误的原因是什么？我应该在哪里查看，或者我应该尝试采取哪些步骤来缩小发生的范围？

我最近从 Ruby 2.2.2 升级到 2.2.4，但是这个错误并没有立即出现。最近对该应用程序的其他更改仅限于 js、css 和 ERB 视图文件。

我的 Gemfile：

source 'https://rubygems.org'

ruby '2.2.4'

这只是一条由状态机引起的警告消息 gem。

这将在 Spree 3.0.8 中修复。抱歉给您带来不便！
