设置NPM源

npm的国际源太慢了，尤其是更新gitbook的时候，无法忍受。 通过更换国内源，速度快很多。

1. 配置npm源地址，更换为淘宝源

   $ npm config set registry https://registry.npmmirror.com
   

2. 查看是否配置成功

   $ npm config get registry
   https://registry.npmmirror.com/
   

3. 测试源

$ npm info underscore

underscore@1.13.7 | MIT | deps: none | versions: 54
