jQuery 未在 bundle.js 中定义

Question

我已经在这个问题上停留了好几天了，我已经尝试了几十种不同的修复方法。首先，我使用 Hugo、Webpack、Node.js 和 Babel。目前，至少一切都在编译，但是当我查看本地主机控制台时，我看到了这些错误：

Uncaught ReferenceError: jQuery is not defined

现在我对 post 的主要推理是为了解决 jQuery 问题，但深入了解另一个问题也很棒，因为我也已经坚持了一段时间嗯。

webpack.config.js

const path = require('path');
const webpack = require('webpack');
// const WebpackManifestPlugin = require('webpack-manifest-plugin');

module.exports = {
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: ['babel-loader'],
            }
        ]
    },
    entry: './assets/js/script.js',
    output: {
        path: path.resolve(__dirname, 'assets', 'js'),
        filename: 'bundle.js',
    },
    externals: {
        jquery: 'jQuery',
    },
    /*    plugins: [
           new webpack.ProvidePlugin({
            $: 'jquery',
            jQuery: 'jquery'
            })
        ]*/
};

我从 script.js（又名主 js 文件）导入：

app.use("/static", express.static('./static/'));
import $ from "../plugins/jquery/jquery.min.js";
import jQuery from "../plugins/jquery/jquery.min.js";
import "../plugins/@popperjs/core/lib/popper.js";
import "../plugins/google-map/map.js";
import "../plugins/magnific-popup/jquery.magnific-popup.min";
import Shuffle from "../plugins/shuffle/shuffle.min.js";
import "../plugins/slick/slick.min.js";
import lozad from "lozad";
//Pricing Scripts
import "../js/pricing/boosting.js";
import "../js/pricing/tourneyTitle.js";
import "../js/pricing/placements.js";
import "../js/pricing/coaching.js";
/* ========================================================================= */
/*  jQuery load initialize
/* ========================================================================= */

window.$ = require('../plugins/jquery/jquery.min');
window.jQuery = $;
require('./script.js');

/* ========================================================================= */
/*  shuffle load initialize
/* ========================================================================= */

const shuffleInstance = new Shuffle(document.getElementById('grid'), {
    itemSelector: '.js-item',
    sizer: '.js-shuffle-sizer',
});

/* ========================================================================= */
/*  lazy load initialize
/* ========================================================================= */

const observer = lozad(); // lazy loads elements with default selector as ".lozad"
observer.observe();

为我的主要 js 源调用包

<script src="./assets/js/bundle.js"></script>

请注意，这不在 static/assets 中，因为当我尝试它时它不起作用并给我一个错误，说你不能将静态文件发送到客户端或网络（类似的东西）。我的资产目录相当于我认为的 src 目录。

“jQuery 未定义”错误通常意味着您没有加载 jQuery 库。我猜你在尝试使用 ES6 Import 语法？

import { $, jQuery } from 'jquery'; 类型语句取决于您使用的 jQuery 版本，请检查（我不知道您使用的 jQuery 是什么版本），还有 jQuery import好像有点不一样？参见上面的导入语句。
为简单起见，您还可以测试传统的 jQuery 导入语句： <script type="text/javascript" src="https:// CDN LINK HERE "></script> and see if 您可以获得在控制台中运行的基本 jQuery 语句。

对不起，我的英语不是最好的，但以上内容可能有助于调试。

一定要告诉我。
