业务逻辑是：
进来界面有个弹窗，是否展示为isShowDialog，它的初始值是跟着store数据变化

代码如下：

<template>
    <diglog v-if="isShowDialog" @close="isShowDialog = false"/>
</template>

import {mapState} from 'vuex'
export default {
    computed: {
        ...mapState({
            nameAuth: (state) => state.user.nameAuth
        }),
        isShowDialog(){
            return this.nameAuth != 1
        }
    }
}

如果关闭弹窗，就会导致报错Computed property "nameAuth" was assigned to but it has no setter.
