vue2 observer

一、初始化项目

命令行 npm init -y

二、安装webpack及相关插件

命令行 npm install webpack webpack-cli webpack-dev-server html-webpack-plugin -D

三、配置文件

1.package.json文件

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "dev": "webpack serve",
  "build": "webpack"
}

**注意：**webpack5.x.x dev配置稍有变化 webpack5之前dev配置webpack-dev-server --config
执行命令npm run dev 发现报错： Error: Cannot find module 'webpack-cli/bin/config-yargs’
查阅资料发现webpack5.x.x dev配置为 webpack serve 如还有错误请到 git issues
