出现这个原因的报错是因为下拉框的key值不是唯一的
<FormItem label="学校" prop="schoolName">
<Select v-model="showEditForm.schoolId" placeholder="Select your school">
<Option v-for="schoolNameId in schoolNameIds" :label="schoolNameId.schoolName"
:value="schoolNameId.schoolId" :key="schoolNameId.schoolId">
{{schoolNameId.schoolName}}
</Option>
</Select>
</FormItem>
:key="schoolNameId.schoolId 必须是唯一的才行
