我有两个组件以相同的方式工作以进行添加，更新，删除...，但是我在此组件中仅具有删除存在关键问题。我可以添加和更新教室，但不能删除。我一直看到此错误：

我的ClassroomComponent.vue是：
<template>
...
<table class="table" v-if="classrooms">
<thead>
<tr>
<th>id</th>
<th>Classroom number</th>
</tr>
</thead>
<tbody>
<tr v-for="(classroom, index) in classrooms" :key="index">
<td>{{classroom.id}}</td>
<td>{{classroom.description}}</td>
<td><button @click="loadUpdateClassroomModal(index)" class="btn btn-info">Edit</button></td>
<td><button @click="deleteClassroom(index)" class="btn btn-danger">Delete</button></td>
</tr>
</tbody>
</table>
...
</template>
<script>
export default {
data(){
return {
classroom:{
description: ''
},
classrooms: [],
uri: 'http://127.0.0.1:8000/classrooms/',
errors: [],
new_update_classroom: [],
toastr: toastr.options = {"positionClass": "toast-top-full-width"}
}
},
methods: {
...
deleteClassroom(index){
let confirmBox = confirm("Do you really want to delete this?");
if(confirmBox == true){
axios.delete(this.uri + this.classrooms[index].id)
.then(response=>{
this.$delete(this.classrooms, index);
toastr.success(response.data.message);
}).catch(error=>{
this.errors.push(error);
});
}
},
loadClassrooms(){
axios.get(this.uri).then(response=>{
this.classrooms = response.data.classrooms;
});
},
resetClassroomData(){
this.classroom.description = '';
}
},
mounted(){
this.loadClassrooms();
}
}
</script>

正如我所说，我还有另一个完全使用相同结构的组件。我不明白我试图在这里找到一些答案：[Vue warn]: Avoid using non-primitive value as key, use string/number value instead，Avoid using non-primitive value as key, use string/number value instead. in VueJS等，对此没有任何解释。
