npm ERR! network If you are behind a proxy, please make sure that the

發生錯誤：
解決辦法
1、執行：
npm config get proxy
npm config get https-proxy
如果返回值不為null，繼續執行：
(要確保兩個返回值都是null才可以，否則就要執行下面的代碼)
npm config set proxy null
npm config set https-proxy null
2、執行：
npm config set registry http://registry.npmjs.org/
然后執行下面的代碼就可以安裝cnpm了
npm install -g npm --registry=https://registry.npm.taobao.org
