之前我们这样使用，来修改ui组件的样式，但是有一个警告
<style scoped>
::v-deep .labelinput .el-form-item__label {
/* 样式定义 */
}
</style>
下面这样
[@vue/compiler-sfc] ::v-deep usage as a combinator has been deprecated.
Use :deep(<inner-selector>) instead of ::v-deep <inner-selector>.
修改后是这样写
<style scoped>
:deep(.labelinput .el-form-item__label){
/* 样式定义 */
}
</style>
