node.js - 无法运行此 nodejs 代码？

Question

我试图运行这个简单的代码，但我一直在出错......我真的不知道有什么问题。在我看来非常好...？谢谢！

    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);
    });

控制台错误是这样的：

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

就我而言，我有

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

一旦我删除了 http 行，它就对我有用。所以，我只离开了

var path=require('path');

我正在研究 express、mongodb、socket.io。
