vue组件报Missing required prop: "value"错误

Question

<template>
  <div class="box-info-module" :class="index?'border':''">
    <div class="info-hd">
      <span class="keys">{{index}}</span>
      <h5>{{title}}</h5>
    </div>
    <transition name="fade">
      <div class="info-bd" v-if="collapse">
        <slot></slot>
      </div>
    </transition>
  </div>
</template>
export default {
    data() {
        return {
            collapse: true
        };
    },
    props: {
        index: [String, Number],
        title: { type: String },
        icon: { type: String, default: "el-icon-minus" }
    },
    filters: {},
    components: {},
    watch: {},
    computed: {},
    methods: {
        toggleShowBox() {
            this.collapse = !this.collapse;
        }
    },
    mounted() {}
};

这是组件代码，我在其他页面用的时候报Missing required prop: "value",查了百度说没绑值，但我这个不需要绑定，请问这是什么毛病，如何解决呢，感谢
