官方文档贴出来的配置参数，写法错误

改成一下配置参数即可

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');

module.exports = {
    mode: 'development',
    entry: {
        app: './src/index.js',
        print: './src/print.js'
    },
    output: {
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist'),
        // publicPath: '/'
    },
    devtool: 'inline-source-map',
    devServer: {
        contentBase: './dist',
        open: false, //自动打开浏览器
        compress: true, //启动Gzip压缩
        port: 8080, //端口号8080
        quiet: true //静默打开
    },
    plugins: [
        new CleanWebpackPlugin(),
        new HtmlWebpackPlugin({
            title: 'Output Management'
        })
    ],
    module: {
        rules: [{
            test: /\.css$/,
            use: ['style-loader', 'css-loader']
        }, {
            test: /\.(png|jpg|svg|gif)$/,
            use: ['file-loader']
        }, {
            test: /\.(woff|woff2|eot|ttf|otf)$/,
            use: ['file-loader']
        }, {
            test: /\.(csv|tsv)$/,
            use: ['csv-loader']
        }, {
            test: /\.xml$/,
            use: ['xml-loader']
        }]
    }
};

这样，报错问题就解决啦。
