count.js中的代码如下：
export default function count(x,y) { return x - y; }sum.js中的代码如下：
export default function sum(...args) { return args.reduce((p, c) => p + c , 0) }main.js中的代码如下：
import count from "./js/count"; import sum from "./js/sum"; console.log(count(2,1)); console.log(sum(1,2,3,4))index.html中代码如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Webpack</title> </head> <body> <h1>hello webpack</h1> <script src="../src/main.js"></script> </body> </html>以上四个文件的目录架构如下所示：
下面依次执行命令如下：
npm init -y
(.venv) PS I:\python\Webpack> npm init -y Wrote to I:\python\Webpack\package.json: { "name": "webpack", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" "keywords": [], "author": "", "license": "ISC", "type": "commonjs" }npm i webpack webpack-cli -D
(.venv) PS I:\python\Webpack> npm i webpack webpack-cli -D added 119 packages, and audited 120 packages in 23s 19 packages are looking for funding run `npm fund` for details found 0 vulnerabilitiespackage.json中的代码如下：
{ "name": "webpack_chen", "version": "1.0.0", "description": "", "main": "./src/main.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": "ISC", "type": "commonjs", "devDependencies": { "@babel/core": "^7.28.6", "@babel/preset-env": "^7.28.6", "babel-loader": "^10.0.0", "webpack": "^5.104.1", "webpack-cli": "^6.0.1" } }npx webpack ./src/main.js --mode=development
运行这条命令后，就出现了错误提示，如下：
(.venv) PS I:\python\Webpack> npx webpack ./src/main.js --mode=development asset main.js 1.54 KiB [emitted] (name: main) ./src/main.js 115 bytes [built] [code generated] [1 error] ERROR in ./src/main.js 1:0 Module parse failed: 'import' and 'export' may appear only with 'sourceType: module' (1:0) You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders > import count from "./js/count"; | import sum from "./js/sum"; | webpack 5.104.1 compiled with 1 error in 105 ms在网上各种搜索解决方案，如下：
module.exports = { >> mode: 'development', >> resolve: { >> fullySpecified: false, // 允许 .js 文件使用 import/export 而不带扩展名 >> };这个方案不管用 ，出现各种错误
npm install babel-loader @babel/core @babel/preset-env --save-dev
这个方案也使用了，还是出问题，如下：
又试用着在package.json中删除
"type": "commonjs",咦，这次居然成功了
