[超详细]npm更换下载源
一. 临时换源
有时只需要临时换源进行插件的下载，可以采用如下方式

npm –registry https://registry.npmmirror.com install [依赖的名称]
二.持久换源
1.下载cnpm方式
cnpm是由淘宝团队开发的，‌作为一个完整的npmjs.org镜像，‌用户可以用它来替代官方的npm（‌Node Package Manager）‌，‌且它是只读的。‌

使用阿里定制的 cnpm 命令行工具代替默认的 npm

npm install -g cnpm –registry=https://registry.npm.taobao.org
检测cnpm版本，如果安装成功会显示cnpm的基本信息

cnpm -v
安装完成后，以后安装插件使用 cnpm install 即可

2.使用set registry命令方式
查看当前源

npm config get registry
更换npm源为国内淘宝镜像

npm config set registry https://registry.npmmirror.com/
如果要还原成官方默认源

npm config set registry https://registry.npmjs.org/
3.使用nrm管理npm源
nrm 是一个 npm 源管理器，允许你快速地在不同的 npm 源间切换

安装nrm源管理工具

npm install -g nrm
查看nrm配置

nrm里默认有一些镜像源的配置

带 * 即为当前使用的源地址

nrm ls

切换不同镜像(例如切换淘宝镜像)

nrm use taobao
测试镜像速度

nrm test taobao
使用nrm添加镜像地址

nrm add [name] [url]

[name]替换成镜像名称

[url]替换成镜像地址
删除nrm镜像

nrm del [name]

[name]替换成镜像名称
