nodejs使用require('request')模块发送数据，报错

Question

var request = require('request');

request('http://www.baidu.com', function (error, response, body) {

    console.log('error:', error); // Print the error if one occurred

    console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received

    console.log('body:', body); // Print the HTML for the Google homepage.

});

这是官网上的实例，但是我这边报错。error: Error: Invalid protocol: null
不知道什么协议的原因
官方githubrequest

应该是cnpm的锅，用npm重新安装request模块，成功运行了
