NPM-安装报错connect ETIMEDOUT

解决方案

1. 报错信息request to https://registry.npm.taobao.org/yarn failed, reason: connect ETIMEDOUT

1、npm set strict-ssl false
2、设置代理
npm config set proxy http://xxx:xxx@openproxy.ali.com:8080

2. yarn install报错’vue-cli-service’ 不是内部或外部命令，也不是可运行的程序

 yarn config set strict-ssl false
 yarn install

常用NPM YARN操作

2. npm如何在安装的时候指定源

npm install -g [email protected] --registry=https://registry.npm.taobao.org

3. 如何查看设置registry和proxy、配置

npm config get
查看和设置镜像
npm get registry
npm config set registry https://registry.npmjs.org/
npm config set ELECTRON_MIRROR “https://npm.taobao.org/mirrors/electron/”
npm config get ELECTRON_MIRROR
npm config delete ELECTRON_MIRROR
设置代理
npm config set proxy http://server:port
npm config set https-proxy http://server:port
查看代理
npm config get proxy
npm config get https-proxy
删除代理
npm config set proxy null
npm config set https-proxy null
yarn设置代理
yarn config set proxy http://xxx:[email protected]:8080
yarn删除代理
yarn config delete proxy
