无法使用RSpec测试获取水豚截图

我查阅了Github文档，通过谷歌搜索找到了答案，但没有找到为什么水豚截图没有保存任何失败截图的答案

这是我目前为我的应用程序所做的设置

end

我尝试了几种不同的方法来实现这一点，但我始终无法获得一个屏幕截图来避免失败。我可以手动调用screenshot函数，但是考虑到gem应该在测试失败时自动生成，我觉得有些不对劲。有趣的是，我可以让宝石的黄瓜部分工作得很好。其他人有没有遇到过让水豚截图与RSpec合作的问题？如果有任何帮助，我们将不胜感激。

我建议用一个可重复性最低的示例来打开问题。

您是否可以将代码示例减少到重新产生问题的最小示例，以及您可能收到的任何错误消息（或指定您没有收到任何错误消息）？看看这是否会使问题变得更简单。而且，我根本没有收到任何错误消息。这就好像需要注册的任何挂钩都没有正确注册一样。感谢您让我知道如何修复
