在Rail的黄瓜中键入错误运行功能
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)
这个错误有一个巨大的堆栈跟踪，但它不指向任何特定的东西，除了缺少的需求。 这是跟踪：

命令失败，状态为（1）：[/System/Library/Frameworks/Ruby.framework / ...]
我找到了这个问题的答案，这是一个与mySQL geoSpatial插件和我的模式的类名冲突 。
我有一个名为Point的课程，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。 这个插件还定义了一个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！
