1. webpack.config.js
   其中 imagemin-gifsicle imagemin-jpegtran imagemin-optipng imagemin-svgo 这几个插件不太容易能够下载下来，可私聊我单独发，或者访问我主页，我上传的资源，其中有个关于webpack图片压缩的插件下载即可。下载地址：https://download.csdn.net/download/qq_45142260/85709385
   webpack.config.js文件是 把webpack.dev.js和webpack.prod.js合并之后的文件，这样会使文件比较整洁一点

2. .eslintrc.js

module.exports = {
  root: true,
  // 启用node环境变量
  env: {
    node: true,
  },
  // 继承 vue3 和 eslint 官方规则
  extends: ["plugin:vue/vue3-essential", "eslint:recommended"],
  // 解析选项
  parserOptions: {
    parser: "@babel/eslint-parser",
  },
};

3. babel.config.js

module.exports = {
  // 继承vue官方规则
  presets: ["@vue/cli-plugin-babel/preset"],
};

4. package.json

"browserslist": [
    "last 2 version",
    "> 1%",
    "not dead"
  ],
  "scripts": {
    "start": "npm run dev",
    "dev": "cross-env NODE_ENV=development webpack serve --config ./config/webpack.config.js",
    "build": "cross-env NODE_ENV=production webpack --config ./config/webpack.config.js"
  },
