Rail的Cucumber中的Type Error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)

此错误有大量堆栈跟踪，但除缺少需求外，它没有指向任何特定的内容。 这是跟踪：

我找到了解决此问题的方法，这是与mySQL geoSpatial插件和我的架构发生类名冲突 。

我有一堂名为Point的课，一切都很高兴。 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Point类。

冲突导致黄瓜失败。

如果您在自己的应用程序中看到此错误，请查找重复项！
