我有一些问题与bootstrap 5和NPM.网站设计使用引导和工程，但不是所有的JS（下拉，模态等...），我只是想学习热导入JS BS捆绑没有CDN.有人可以帮助我，请？感谢您的时间

我的步骤：

npm install bootstrap@5.0.0-alpha1
npm install popper.js --save
npm intsall node-sass --save-d

包.json：

{
  "name": "xlf",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "dev": "./node_modules/.bin/webpack --watch",
    "sass": "node-sass --watch src/scss -o dist/css --output-style nested"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "bootstrap": "^5.0.0-alpha1",
    "popper.js": "^1.16.1"
  },
  "devDependencies": {
    "node-sass": "^5.0.0",
    "webpack": "^5.26.0",
    "webpack-cli": "^4.5.0"
  }
}

网络包配置js

const path = require('path');

module.exports = {
   entry: './src/js/app.js',
   output: {
      path: path.resolve(__dirname, 'dist','js'),
      filename: 'app.js',
   },
   mode: 'production',
   module: {
      rules:[
       {
          test: /.(scss|css)$/,
          use:
          [
             {
                options: { reloadAll: true },
             },
             'css-loader',
             'sass-loader',
             'node-sass'
          ]
       }
      ]
   }
 };

src/js/app.js

import 'bootstrap';

src/scss/app.scss

@import '../../node_modules/bootstrap/scss/bootstrap.scss';
