npm的connect ETIMEDOUT 104.16.22.35:443

安装node之后，以为npm虽然下载慢一点，可是还能接受，就没有安装cnpm。直达本身从github clone了几个开源程序，发现npm install失败了。报错npm ERR! code ETIMEDOUT
npm ERR! errno ETIMEDOUT
npm ERR! network request to https://registry.npmjs.org/@nodelib%2ffs.stat
, reason: connect ETIMEDOUT 104.16.20.35:443
npm ERR! network This is a problem related to network connectivity.

gs.

错误这么多，可是问题在于须要使用cnpm

执行npm install -g cnpm --registry=https://registry.npm.taobao.org

再执行cnmp install

就ok了
