一、镜像源

        npm默认镜像源是国外的，安装依赖速度较慢，使用国内的镜像源速度会快一些。

1、设置淘宝镜像源：

#最新地址 淘宝 NPM 镜像站喊你切换新域名啦!
npm config set registry https://registry.npm.taobao.org（弃用了）

npm config set registry https://registry.npmmirror.com(新的)

2、查看当前镜像源：

npm config get registry

3、设置官方镜像源：

npm config set registry https://registry.npmjs.org

还可以使用nrm查看和切换镜像

//安装nrm,一定要全局安装
npm install -g nrm

//nrm查看所有镜像源命令，带*即为当前使用的源

nrm ls
  npm ---------- https://registry.npmjs.org/
  yarn --------- https://registry.yarnpkg.com/
  tencent ------ https://mirrors.cloud.tencent.com/npm/
  cnpm --------- https://r.cnpmjs.org/
* taobao ------- https://registry.npmmirror.com/
  npmMirror ---- https://skimdb.npmjs.com/registry/
 
//如果使用nrm ls发现全面都没有带*，则可以参考最后面的教程
 
//切换镜像源命令
nrm use xxx  //例：nrm use taobao 就可以切换自己想用的镜像源了
 
//当前使用的源
nrm current

taobao

二、使用cnpm安装

 npm install -g cnpm --registry=https://registry.npmmirror.com
 
 # 注册模块镜像
 npm set registry https://registry.npmmirror.com  
 
 // node-gyp 编译依赖的 node 源码镜像  
 npm set disturl https://npmmirror.com/dist 
 
 // 清空缓存  
 npm cache clean --force  
 
 // 安装cnpm  
 npm install -g cnpm --registry=https://registry.npmmirror.com
