Rail's Cucumber 中的类型错误运行功能

Question

我正在尝试为我的 Rails 应用程序运行 Cucumber 并不断收到此错误：

> superclass mismatch for class Point (TypeError)

此错误有一个巨大的堆栈跟踪，但除了缺少需求之外，它没有指向任何特定内容。这是跟踪：

Answer 1

我找到了这个问题的答案，它是类名与 mySQL geoSpatial 插件和我的架构冲突。

我上了一堂名为 Point 的课，一切都很开心。然后我添加了（非常酷的）geoSpatial 插件来使用 mySQL 的地理索引功能。该插件还定义了一个Point 类。

冲突导致 Cucumber 失败。

如果您在自己的应用程序中看到此错误，请查找重复的错误！
