node不管你喜不喜欢、有没有了解过，但在项目中却总是会用到，开源的集成太多了.不管是哪一个框架，composer安装后，总会给你集成一大堆的东西，不管你有没有了解过，后期开发会不会用到，全给你集成进去了（因为框架会用到）。
laravel也是带这样的坑，laravel使用了mix，必须要用到node，没啥关系的两种开发环境，就这样硬集成一块去了。node环境出问题，影响了laravel无法正常安装使用，你明明用的是laravel，但却要去解决node的问题。坑不坑？其实挺坑的！
回到正题，还是laravel-shop的安装问题，换了一台机，又得重新再安装一遍，前台页面还是报Mix错误，查了node跟npm的版本，比较低，npm install -g npm升级又升级不了！执行npm命令（任何一个），就报以下这个错：
zu@he:/var/www/html/laravel-shop$ npm update
/usr/local/lib/node_modules/npm/bin/npm-cli.js:85
let notifier = require('update-notifier')({pkg})

zu@he:sudo apt-get remove nodejs
zu@he:curl -sL https://deb.nodesource.com/setup_8.x | sudo bash
zu@he:sudo apt-get update
zu@he:sudo apt-get install nodejs
zu@he:sudo npm install npm -g再重新在网站根目录删除node_modules后，再执行npm install，却一直报下面的错误

是终解决方案：
#使用其它的镜像，之前用了淘宝的，切换dns为233.5.5.5都不行，再换为其它的吧！
npm config set registry http://r.cnpmjs.org
#完成后，重新执行install
npm cache verify && npm install
#最后重新启动一下npm
npm run production最后感谢一下以下作者
