查看当前支持切换的源

➜  /Users/zhangzhi/code  >nrm ls
  npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
* taobao - http://registry.npm.taobao.org/
  edunpm - http://registry.enpmjs.org/
  eu ----- http://registry.npmjs.eu/
  au ----- http://registry.npmjs.org.au/
  sl ----- http://npm.strongloop.com/
  nj ----- https://registry.nodejitsu.com/
  pt ----- http://registry.npmjs.pt/

上面列出了可选的9个源，还用 * 号标记出了当前我使用的源

切换指定的源

假如现在我想把 taobao 源 切换成 eu 的镜像源( 貌似走的教育网，我也不确定速度是不是快，只是演示切换)

➜  /Users/zhangzhi/code  >nrm use eu
Registry has been set to: http://registry.npmjs.eu/

切换后的源列表

➜  /Users/zhangzhi/code  >nrm ls
  npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
  taobao - http://registry.npm.taobao.org/
  edunpm - http://registry.enpmjs.org/
* eu ----- http://registry.npmjs.eu/
  au ----- http://registry.npmjs.org.au/
  sl ----- http://npm.strongloop.com/
  nj ----- https://registry.nodejitsu.com/
  pt ----- http://registry.npmjs.pt/

可以看到源已经切换成了 eu

你还可以添加已知的源，或者删除
