NODE.JS：尝试在 atom 上运行我的第一个 nodejs

Question

i'm having some trouble running this simple code on atom:

  *var http = require('http');
  http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.end('Hello World!');
}).listen(8080);* 

and it shows the following error:

node:events:498 throw er; // Unhandled 'error' event ^ Error: listen EADDRINUSE: address already in use:::8080 at Server.setupListenHandle [as _listen2] (node.net:1330:16) at listenInCluster (node.net:1378:12) at Server.listen (node.net:1465:7) at Object.
