最近在新下載了一個專案，需要 npm i 下載依賴，，但是一直報錯，， 首先用cnpm源下載

$ npm install -g npm npm ERR! code E500 npm ERR! 500 Internal Privoxy Error: [email protected] 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

換成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 npm ERR! network This is a problem related to network connectivity. npm ERR! network In most cases you are behind a proxy or have bad network settings. npm ERR! network npm ERR! network If you are behind a proxy, please make sure that the npm ERR! network ‘proxy’ config is set properly.

於是我想到了我之前好像設定了網路代理 於是跟著做了一下，，果不其然 設定完之後重新npm i
