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

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
