这两天摆弄webpack，躺过很多坑，直到今天看了一位博主的文章才得以解决。他对配置中的各个部分做说明。
下面的配置99.9%抄自博主: https://www.cnblogs.com/nianyifenzhizuo/p/10271001.html
安装package.json中的node-sass可能因为网络原因不能成功安装
报错信息有一大串，其中提及python和gyp，其实不用去安装他们。只要执行下面的命令：
npm set sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
npm i node-sass -D
以下为一个vue项目的基本配置：
项目根目录：
package.json
postcss.config.js
.babelrc
项目根目录=>build文件夹

const isDev = process.env.NODE_ENV === ‘production‘
let pluginsConfig = [
new VueLoaderPlugin(),
