Method “computed” has type “object” in the component definition. Did you reference the function correctly?
意思是：
方法“computed”在组件定义中具有类型“object”。你正确地引用了函数吗？
出现这样的问题就是 将methods方法报裹住了computed
computed: {
carId() {
if(this.addForm.goods_cat.length===3){
return this.addForm.goods_cat[2]
console.log( this.addForm.goods_cat);
}
return null
}
