win10安装http-server失败

本人使用window10，再安装完node.js后安装http-server一直提示超时，出现如下页面

C:\Users\11967>npm install http-server -g
npm ERR! code ETIMEDOUT
npm ERR! errno ETIMEDOUT

使用该命令进行安装cnpm(npm/cnpm都是包管理工具，其中npm是国外版本，cnpm是国内版本)也是不成功

C:\Users\11967>npm install -g cnpm

请教了前端的朋友，可以通过安装淘宝镜像再进行安装http-server

C:\Users\11967>npm install -g cnpm --registry=https://registry.npm.taobao.org
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

+ cnpm@6.1.1
added 16 packages from 2 contributors, removed 17 packages and updated 40 packages in 19.801s

C:\Users\11967>cnpm i -g http-server    //安装http-server

安装成功后，进入你要选择的文件夹中打开命令窗口，执行http-server就可以启动服务，使用ctrl+c则是终止服务
