npm 配置代理
npm config set proxy http://[ip]:[port]

npm config set https-proxy http://[ip]:[port]

如果代理需要认证的话可以这样来设置
npm config set proxy http://username:password@server:port

npm config set https-proxy http://username:pawword@server:port

查看npm配置

npm config get
or
npm config list

清除npm代理

npm config delete proxy
and
npm config delete https-proxy
