[英]Error: Cannot find module “moduleIntro.js” when running “http”
I tried a basic beginner program in Node.Js where I wanted to use the built-in module 'http'.我在 Node.Js 中尝试了一个基本的初学者程序,我想在其中使用内置模块“http”。 After executing a basic program of http.createServer().
执行 http.createServer() 的基本程序后。 Below is my source code.
下面是我的源代码。
var http = require('http');
http.createServer(function (req, res) {
res.write('Hello World!');
res.end();
}).listen(8080);
When running the code in cmd it didn't run and displayed the following error.在 cmd 中运行代码时,它没有运行并显示以下错误。
events.js:287
throw er; // Unhandled 'error' event

Ok, it's not problem in your code actually 8080 already running anywhere else so you can't run the same port number at a time so just close all running process Or you just shut down your PC and run again the problem will be resolve.好的,您的代码实际上没有问题 8080 已经在其他任何地方运行,因此您不能一次运行相同的端口号,因此只需关闭所有正在运行的进程,或者您只需关闭 PC 并再次运行,问题就会得到解决。
