1、错误场景:安装vue插件的时候,报错,提示安装最新版本

npm ERR! Make sure you have the latest version of node.js and npm installed.

npm ERR! You can get information on how to open an issue for this project with:
npm ERR! npm bugs muse-ui
npm ERR! Or if that isn't available, you can get their info via:
npm ERR! npm owner ls muse-ui
npm ERR! There is likely additional logging output above.
npm ERR! Please include the following file with any support request:

2、查看版本
npm -v
3、安装最新版本(全局)
npm install -g npm
4、安装指定版本(@后面跟版本号)
npm -g install npm@6.9.0
5、node版本升级
官网下载最新安装包,安装覆盖
6、安装另外一个包的时候,还是有报错,
C:\Users\Administrator.CE-20151109NQJC\AppData\Roaming\npm
npm WARN deprecated autoprefixer-loader@3.2.0: Please use postcss-loader instead of autoprefixer-loader

错误原因分析:
使用命令npm install xx安装包的时候,默认是从npm的镜像源服务器进行下载的,该服务器是放在国外,很容易安装失败,因此全局安装nrm镜像源管理器,nrm里面存放了多个镜像源服务器
npm isntall nrm -g
问题解决:
先清空缓存,再重新安装
npm cache clearn --force
npm install
