开发React Native时，通过下面命令将npm设置成淘宝镜像
npm config set registry https://registry.npm.taobao.org
npm config set disturl https://npm.taobao.org/dist
现在需要将淘宝镜像去掉，还原成官方镜像，请问如何处理？
npm config delete registry
npm config delete disturl
或者
npm config edit
找到淘宝那两行,删除手动的太麻烦了，一般用 https://www.npmjs.com/package/nrm 做切换
$ nrm ls
