npm install时报错 reason: connect ETIMEDOUT
在VS code中导入新项目，执行npm install时报错：
npm warn old lockfile Could not fetch metadata for @antv/coord@0.1.0 FetchError: request to https://registry.npmjs.org/@antv%2fcoord failed, reason: connect ETIMEDOUT 150.242.56.251:443

npm warn old lockfile }原因：由于访问国内访问npm的资源库地址（https://registry.npmjs.org）连接超时导致。
解决办法：
1）将npm的镜像源设置为国内的即可（任选一种）：
# 更换成淘宝镜像源
npm config set registry https://registry.npm.taobao.org# 更换成阿里镜像源
npm config set registry https://npm.aliyun.com/# 更换成华为镜像源
npm config set registry https://mirrors.huaweicloud.com/repository/npm/# 更换成腾讯镜像源
npm config set registry http://mirrors.cloud.tencent.com/npm/2）设置完成后，重新执行npm即可。
扩展：通过下面命令可查看当前的镜像源：
npm config get registry
