1：正确步骤

2：这里其实我自阐述一下

这里最好注释掉

const path = require('path')
const defaultSettings = require('./src/settings.js')

function resolve(dir) {
  return path.join(__dirname, dir)
}

const name = defaultSettings.title || 'vue Element Admin' // page title

// If your port is set to 80,
// use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following method:
// port = 9527 npm run dev OR npm run dev --port = 9527
const port = process.env.port || process.env.npm_config_port || 9527 // dev port

// All configuration item explanations can be find in https://cli.vuejs.org/config/

到这里应该是没错了，但是小编个人出现了一直打包，但是界面报404错误

我后台部署用了docker
然后nginx是docker容器里的，所以我也要把代码复制进行
于是我执行了

docker cp /home/web f93:/home/web

没错，就是这个指令害的
第一次容器里没有web文件夹，新建web文件夹，第一次没问题
之后修改，在执行，他在web文件夹里新建了web文件夹
所以每次打包，复制到容器里去，其实改的都不是nginx指的位置

应该是执行

docker cp /home/web f93:/home/

最后得知：可以使用docker -v 或者volume进行挂载，关联，不用复制文件到容器里去
最后就是自己对shell的cp的使用不熟练
