Computed property “XXX“ was assigned to but it has no setter

报错原因：vuex

1.组件中v-model=“XXX”，而XXX是vuex state中的某个变量

2.vuex中是单项流，v-model是vue中的双向绑定，在computed中只经过get获取参数值，没有set没法改变参数值

解决办法：

1.在computed中设置get和sets

<input v-model="type">computed: {type: {get () {return this.$store.getters.type},set (val) {this.$mit('app/SET_TYPE', val)}}},

2.使用mapGetters，把v-model改为:value

<input :value="type">import {mapGetters } from "vuex";computed: {...mapGetters(["type"]),},
