npm镜像源

因为 npm 默认的源是在国外，我们访问时会比较慢，一般都会使用淘宝的镜像，或者有些有公司自己的镜像，这就涉及到切换源的操作，总结一下这些操作。

1、查看当前使用的镜像源

npm config get registry

2、修改镜像源

方式1：npm命令修改

npm config set registry https://registry.npmmirror.com/

方式2： 第三方工具nrm管理镜像源（推荐）

nrm可以帮助你轻松地添加、删除、查询、切换所有的Yarn Registries

安装 nrm：

npm install -g nrm

列出所有镜像源：

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/

切换镜像：

nrm use taobao
SUCCESS The registry has been changed to 'taobao'.

新增镜像：

nrm add aliyun http://maven.aliyun.com/nexus/content/groups/public

删除镜像：

nrm del taobao

测试延迟（访问速度）：

yrm test aliyun

yarn镜像源

执行命令时，yarn 默认是去 npm/yarn 官方镜像源（国外）获取资源，所以速度较慢甚至不可用，解决该问题需要修改默认配置为国内镜像。

1、查看当前使用的镜像源

yarn config get registry

2、修改镜像源

方式1：yarn命令修改

yarn config set registry https://registry.npm.taobao.org/

方式2： 第三方工具yrm管理镜像源（推荐）

yrm可以帮助你轻松地添加、删除、查询、切换所有的Yarn Registries

安装 yrm：

npm install -g yrm

列出所有镜像源：

yrm ls

  cnpm --- http://r.cnpmjs.org/
  taobao - https://registry.npm.taobao.org/
