vue.config.js 使用

const path = require('path');

function resolve(dir) {
  return path.join(__dirname, dir)
}
//导出路径
module.exports = {
  chainWebpack: config => {
    config.resolve.alias
      .set("@", resolve("src"))
      .set("assets", resolve("src/assets"))
      .set("components", resolve("src/components"))
      .set("imgs", resolve("src/assets/img"))
  },
}

一般如果报错找不到路径 , 看看是不是没有安装path

安装指令  

npm  install  path  --save
