今天创建了一个新项目

{
  "scripts": {
    "start": "webpack-dev-server",
    "build": "webpack --progress --colors"
  },
  "devDependencies": {
    "webpack": "^5.42.0",
    "webpack-cli": "^4.7.2",
    "webpack-dev-server": "^3.11.2"
  }
}

然而启动项目时，却报错了：

Error: Cannot find module 'webpack-cli/bin/config-yargs'

frankie@iMac react-ts %  yarn start                                                                                                                                                           [14:04:47]

然后搜查了一番，有部分人是删除了 node_modules，重新 install 可以跑起来，但这是不对的。

解决方法应该是：

Install the lastest webpack-cli and use webpack serve to run webpack dev server instead webpack-dev-server. #3304

就是说，安装最新的 webpack-cli 并使用 webpack serve 来运行 webpack dev server 而不是 webpack-dev-server。

{
  "scripts": {
    "start": "webpack serve",
    "build": "webpack --progress"
  },
  "devDependencies": {
    "webpack": "^5.42.0",
    "webpack-cli": "^4.7.2",
    "webpack-dev-server": "^3.11.2"
  }
}

改完就能愉快地玩耍了...
