npm設定和取消代理的方法

設定代理

npm config set proxy=http://server:port
npm config set https-proxy https://server:port // https代理設定
npm config set registry=http://registry.npmjs.org      

需要認證的話，設定代理使用者名和密碼

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

取消代理

npm config delete proxy
npm config delete https-proxy
