Der folgende Fehler ist beim Kapseln des Timepickers von element-ui aufgetreten

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "value" 
(found in <ElInput>)

Der Kapselungscode lautet wie folgt:

<template>
  <p class="block">
    <span class="demonstration">时间</span>
    <el-date-picker
      v-model="date"
      type="datetimerange"
      placeholder="Select time range">
    </el-date-picker>
  </p>
</template>

<script>
  export default {
    name:"timepicker",
    data(){
        return{
            date:this.dateValue
        }
    },
    props: {
      dateValue: Array
    },
    computed:{
    }
  }
</script>

Wie folgt verwenden:

<timepicker :date-value="date"></timepicker>

Wenn Sie auf die Zeitsteuerung klicken, um die Zeit auszuwählen, wird ein Fehler gemeldet. Wenn Sie nicht klicken, gibt es kein Problem.
Bitte lassen Sie mich wissen, wie Komponenten mit dem V-Modell gekapselt werden.
