webpack打包jQuery報(bào)錯(cuò)

很長(zhǎng)時(shí)間沒(méi)有學(xué)習(xí)webpack了，最近閑下來(lái)開(kāi)始學(xué)習(xí)webpack最新版，webpack4，跟著官網(wǎng)步驟一步一步敲，竟然出了錯(cuò)，求大神解釋。
我安裝了一些必要的模塊后，安裝了jquery，package.json如下：

{
  "name": "vuetest",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "sideEffects": false,
  "scripts": {
    "build": "webpack --config webpack.prod.js",
    "start": "webpack-dev-server --open --config webpack.dev.js"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "clean-webpack-plugin": "^0.1.19",
    "html-webpack-plugin": "^3.2.0",
    "webpack": "^4.16.5",
    "webpack-cli": "^3.1.0"
  },
  "dependencies": {
    "jQuery": "^1.7.4"
  }
}

webpack.config,js配置如下：

const path = require('path');
const webpack = require('webpack');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const HTMLWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    mode: 'development',
    entry: {
        index: './src/index.js'
    },
    output: {
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist')
    },
    plugins: [
        new HTMLWebpackPlugin({
            template: 'index.html',
            title: 'Code Splitting'
        }),
        new CleanWebpackPlugin(['dist']),
    ]
};

接下來(lái)是我使用jquery的index,js了，如下所示：

import _ from 'lodash';
import { cube } from './math.js';
const $ = require("jQuery");

console.log($)

if(process.env.NODE_ENV) {
    console.log(process.env.NODE_ENV);
}

function component() {
    var element = document.createElement('pre');
    var element2 = _.join(['Hello', 'webpack'], ' ');
    console.log('a' + element2)

    element.innerHTML = [
        'Hello webpack!',
        '5 cubed is equal to ' + cube(5)
    ].join('\n\n');

    return element;
}

document.body.appendChild(component());

我在控制臺(tái)執(zhí)行webpack，然后報(bào)錯(cuò)，我不明白問(wèn)題出在哪里，請(qǐng)大神解決（我甚至刪除了所有模塊，重新下載，卸載了node.js，重新安裝，都是這個(gè)錯(cuò)）
