请问 google 的 puppeteer 模块 和 node.js 自带 的 http、 https 模块 有冲突，怎么解决？

测试代码段如下：

async function puppeteer_promise ( ) {
........var puppeteer = require('puppeteer'); /*** 屏蔽测试 ***/
........return ;
}

async function http_promise ( ) {
........var http = require('http');
........var https= require('https');

........var url = new URL ( "https://www.baidu.com/" ) ;
........var http = ( url.protocol == 'https:' ? https : http ) ; // 重新赋值 http ，判断是 http 还是 https ；
........console.log( "url.protocol：" + url.protocol ) ;

........http.get ( url , function ( res ) { /*** 屏蔽测试 ***/

........}).on('error', function (err) {
................console.log(err);
........});

........return ;
}

async function test_alldata ( ) {

........console.log( "开始测试！" ) ;

........await puppeteer_promise();
........console.log( "puppeteer 结束！" ) ;

........await http_promise();

........console.log( "结束测试！" ) ;

........return ; // 隐式返回 Promise.resolve( ); 函数 ；

}

test_alldata();

报错信息如下：

屏蔽 var puppeteer = require('puppeteer');
或者 屏蔽
........http.get ( url , function ( res ) { /*** 屏蔽测试 ***/

........}).on('error', function (err) {
................console.log(err);
........});
运行就不会报错。

请问各位，知道是怎么回事吗？
有没有什么解决办法啊？
