最近在新下载了一个项目，需要 npm i 下载依赖，，但是一直报错，，
首先用cnpm源下载
$ npm install -g npm
npm ERR! code E500
npm ERR! 500 Internal Privoxy Error: npm@latest
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\zt\AppData\Roaming\npm-cache_logs\2018-09-11T01_15_45_539Z-debug.log
换成npm源
$ npm i
npm ERR! code ECONNRESET
npm ERR! errno ECONNRESET
npm ERR! network request to https://registry.npmjs.org/typescript/-/typescript-2.9.2.tgz failed, reason: socket hang up

于是百度
https://segmentfault.com/q/1010000006696165，找到了这篇文章
于是我想到了我之前好像设置了网路代理
于是跟着做了一下，，果不其然
设置完之后重新npm i
$ npm i
