yarn install 报错 connect ETIMEDOUT 104.16.22.35:443".

 报错信息：An unexpected error occurred: "https://registry.yarnpkg.com/dcmjs/-/dcmjs-0.29.3.tgz: connect ETIMEDOUT 104.16.25.35:443".

 解决方法：更换镜像源

先把node-sass镜像源进行设置成国内的

yarn config set sass-binary-site http://npm.taobao.org/mirrors/node-sass

然后将资源地址设置为淘宝镜像

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

记得查看一下自己是否更改成功

yarn config get registry

 

也可以试试这两个命令

 更改完成后继续 yarn install 即可
