laravel npm run watch报错You may need an appropriate loader to handle this file type

laravel结合vue开发watch的时候报错如下：

ERROR in ./resources/assets/js/components/UserNotifications.vue?vue&type=template&id=c0045994&

laravel对应更改：

D:\phpStudy\PHPTutorial\WWW\forum\node_modules\laravel-mix\src\builder\WebpackConfig.js

let VueLoaderPlugin = require('vue-loader/lib/plugin');

buildPlugins() {
        this.webpackConfig.plugins = this.webpackConfig.plugins.concat(
            webpackPlugins(), new VueLoaderPlugin()
        );

        return this;
    }

再次运行run watch即可正常更新。
