要用到nrm

首先设置环境目录：
set path=d:develop odejs;%path%

暂时不明白这步是干嘛的

然后安装nrm

npm install -g nrm --registry=http://registry.npm.taobao.org

nrm ls

* npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
  taobao - http://registry.npm.taobao.org/
  eu ----- http://registry.npmjs.eu/
  au ----- http://registry.npmjs.org.au/
  sl ----- http://npm.strongloop.com/
  nj ----- https://registry.nodejitsu.com/

然后nrm use taobao现在源已经变成淘宝了
