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
