我正在尝试创建一个模态,但是只有在关闭它时才出现此错误:
[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"

使用ProgressDesconectarModal.vue,showDesconectar是一个数据变量
<panel-desconectar-modal :value="showDesconectar"></panel-desconectar-modal>

这是因为您的道具value中有道具v-model。
请勿这样做,因为这将value在v-model更改时使prop()突变(您只应data使用v-modelafaik 更改值,但在这种情况下,甚至不需要其他data变量)。
从vuejs v2.3.0开始,建议将emit值赋值为parent,以便父级对其进行更改,然后将其传递给子组件。
在v-dialog组件中
删除v-model并替换为:value="value" @input="$emit('input')"
而你的功能:
closeDialog() {
this.$emit('input');
}

在panel-desconectar-modal组件中使用v-model="showDesconectar"。
这将起作用,因为:
