单从错误信息看,在My.ets里面:
首先,有一个方法返回值不是void,也不是任意类型,但它最终没有返回值:[Compile Result] A function whose declared type is neither 'void' nor 'any' must return a value;
其次,使用了两个及以上@Entry修饰符,而Page里面只允许有一个@Entry修饰符:[Compile Result] A page configured in 'main_pages.json' must have one and only one '@Entry' decorator;
最后,build()方法内部应该有一个根容器组件:[Compile Result] There should have a root container component.
