NPM更换国内源
NPM简介
NPM是随同NodeJS一起安装的包管理工具,能解决NodeJS代码部署上的很多问题,常见的使用场景有以下几种:
- 允许用户从NPM服务器下载别人编写的第三方包到本地使用。
- 允许用户从NPM服务器下载并安装别人编写的命令行程序到本地使用。
- 允许用户将自己编写的包或命令行程序上传到NPM服务器供别人使用。
换源
显示当前的镜像网址:
npm get registry
显示:https://registry.npmjs.org/
更换淘宝的镜像网址:
npm config set registry http://registry.npm.taobao.org
再次查看当前镜像:
npm get registry
显示:http://registry.npm.taobao.org/
更换成功!
遇到报错
