ElementUI开发报错，使用el-label的label-width=auto导致。

element-ui开发，报错信息如下：

[Vue warn]: Error in beforeDestroy hook: "Error: [ElementForm]unpected width "

found in ---> <LabelWrap> at packages/form/src/label-wrap.vue

<ElFormItem> at packages/form/src/form-item.vue

<ElForm> at packages/form/src/form.vue

<ElDialog> at packages/dialog/src/component.vue

<UserPower>

<AppMain> at src/layout/components/AppMain.vue

<Layout> at src/layout/index.vue

<App> at src/App.vue

<Root>

解决方法一：

label-width= auto

改为实际宽度，如：label-width="100px"

方法二：

v-show 改为 v-if

PS：暂无效果
