Can't run this nodejs code?

Question

Im trying to run this simple code but I m getting error all the time...I really dont know what's the problem. It seems to me very Ok...? Thanks!

    var http = require(http);
    console.log('Starting');
    var host = '127.0.0.1';
    var port = 1337;

    var server = http.createServer(function(request, response){

            console.log('Receive request: '+ request.url);
            response.writeHead(200, {"Content-type" : "text/plain"});
            response.end("Hello world");


    });
 server.listen(port, host, function(){
        console.log('Listening: ' + host + ':' + port);
    });

Console error is this:

assert.js:98
  throw new assert.AssertionError({
        ^
AssertionError: path must be a string: path must be a string

Answer 1

在您的第一行中，http 周围缺少引号：

var http = require('http');

Answer 2

In my case, I had

var http = require('http');
var path= require('path');

As soon as I deleted the the http line, it worked for me.So, i did leave only

var path= require('path');

I was working on express,mongodb,socket.io.
