webpack

1.cd test
2.npm init
3.npm install webpack -g
4.npm install webpack --save-dev
5.touch webpack.config.js    index.js   index.html
6.webpack 配置
let path = require('path');
let webpack = require('webpack');
module.exports = {
    entry: './index.js',
    output: {
        path: path.join(__dirname, 'dist'), //输出目录的配置，模板、样式、脚本、图片等资源的路径配置都相对于它
        filename: "bundle.js"
    },
    module: {
        rules: [

        ]
    }
};
7.运行webpack报错
npm i -g webpack-cli全局安装
npm install webpack webpack-cli -D本项目安装

8.长用配置
