The code parses and loads... but it still throws an error: NoMethodError: undefined method 'property' for CruiseShip:Class
再对上面的代码进行解析和加载,仍会抛出一个错误:NoMethodError:undefinedmethod “property”for CruiseShip:Class。 也就是说,在CruiseShip方法中没有property方法的定义。

Your code includes some undefined variable that you have used as if it was already defined and initialized.
