vue.runtime.esm.js?2b0e:619 [Vue warn]: Missing required prop: "value"

在开发过程中，突然发现页面console中有报错，报错信息如下

[Vue warn]: Missing required prop: "value"

然后在页面中，把相关的都注释了一遍，左后发现了问题所在

<el-select class="w_80">
    <el-option label="启用" :value="1"/>
    <el-option label="禁用" :value="0"/>
    <el-option label="请选择" :value="-1"/>
</el-select>

修改之后，增加了v-model="where.deleted"，就可以了，报错解决

<el-select v-model="where.deleted" class="w_80">
    <el-option label="启用" :value="1"/>
    <el-option label="禁用" :value="0"/>
    <el-option label="请选择" :value="-1"/>
</el-select>
