(Emitted value instead of an instance of Error) the "scope" attribute for scoped slots have been deprecated and replaced by "slot-scope" since 2.5. The n ot-scope" attribute can also be used on plain elements in addition to <template> to denote scoped slots.
解决方法
检查下你的列表组件里，slot 里的 <template> 上面有个 scope 属性，你改成 slot-scope <template scope="xxx">yyyyyyyy</template> 改成 <template slot-scope="xxx">yyyyyyyy</template> scope 属性在2.5以后的版本中已经废弃， 被 slot-scope 替代 slot-scope 不光可以用在 template 元素上，也可以用在其它元素
vue项目报错如下：(Emitted value instead of an instance of Error)
