请问项目运行时总是出现/sockjs-node/info?t=1473313213585". [WDS] Disconnected!的错误是怎么回事？

webpack.common.js如下

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');

    plugins: [
        new webpack.optimize.CommonsChunkPlugin({
            name: ['app', 'vendor', 'polyfills']
        }),

        new HtmlWebpackPlugin({
            template: 'src/index.html'
        })
    ]
};

package.json scripts start 部分：

"start": "webpack-dev-server --inline --progress --port 8080 --host 0.0.0.0",

webpack-dev-server에 --hot을 추가합니다. 이 옵션은 업데이트를 구성하는 데 사용됩니다.
