未捕获的ReferenceError：require是未定义的

我试图让video上传器在我的服务器上工作，我有节点安装在我的服务器上作为根。

我在我的节点js文件所在的文件夹中安装了以下内容

cd /assets/js npm install socket.io npm install requirejs 

然后我运行节点文件

 ]# node uploader.js info - socket.io started debug - served static content /socket.io.js 

这里是我的uploader.js

  var app = require('http').createServer(handler) , io = require('socket.io').listen(app) , fs = require('fs') , exec = require('child_process').exec , util = require('util') , Files = {}; app.listen(8080); function handler (req, res) { fs.readFile(__dirname + '/index.html', function (err, data) { if (err) { res.writeHead(500); return res.end('Error loading index.html'); } res.writeHead(200); res.end(data); }); } io.sockets.on('connection', function (socket) { socket.on('Start', function (data) { //data contains the variables that we passed through in the html file var Name = data['Name']; Files[Name] = { //Create a new Entry in The Files Variable FileSize : data['Size'], Data : "", Downloaded : 0 } var Place = 0; try{ var Stat = fs.statSync('Temp/' + Name); if(Stat.isFile()) { Files[Name]['Downloaded'] = Stat.size; Place = Stat.size / 524288; } } catch(er){} //It's a New File fs.open("Temp/" + Name, 'a', 0755, function(err, fd){ if(err) { console.log(err); } else { Files[Name]['Handler'] = fd; //We store the file handler so we can write to it later socket.emit('MoreData', { 'Place' : Place, Percent : 0 }); } }); }); socket.on('Upload', function (data){ var Name = data['Name']; Files[Name]['Downloaded'] += data['Data'].length; Files[Name]['Data'] += data['Data']; if(Files[Name]['Downloaded'] == Files[Name]['FileSize']) //If File is Fully Uploaded { fs.write(Files[Name]['Handler'], Files[Name]['Data'], null, 'Binary', function(err, Writen){ var inp = fs.createReadStream("Temp/" + Name); var out = fs.createWriteStream("Video/" + Name); util.pump(inp, out, function(){ fs.unlink("Temp/" + Name, function () { //This Deletes The Temporary File exec("ffmpeg -i Video/" + Name + " -ss 01:30 -r 1 -an -vframes 1 -f mjpeg Video/" + Name + ".jpg", function(err){ socket.emit('Done', {'Image' : 'Video/' + Name + '.jpg'}); }); }); }); }); } else if(Files[Name]['Data'].length > 10485760){ //If the Data Buffer reaches 10MB fs.write(Files[Name]['Handler'], Files[Name]['Data'], null, 'Binary', function(err, Writen){ Files[Name]['Data'] = ""; //Reset The Buffer var Place = Files[Name]['Downloaded'] / 524288; var Percent = (Files[Name]['Downloaded'] / Files[Name]['FileSize']) * 100; socket.emit('MoreData', { 'Place' : Place, 'Percent' : Percent}); }); } else { var Place = Files[Name]['Downloaded'] / 524288; var Percent = (Files[Name]['Downloaded'] / Files[Name]['FileSize']) * 100; socket.emit('MoreData', { 'Place' : Place, 'Percent' : Percent}); } }); }); 

我的客户端代码是

 <div id="UploadBox"> <h2>Video Uploader</h2> <span id='UploadArea'> <label for="FileBox">Choose A File: </label><input type="file" id="FileBox"><br> <label for="NameBox">Name: </label><input type="text" id="NameBox"><br> <button type='button' id='UploadButton' class='Button'>Upload</button> </span> </div> <script src="http://example.com:8080/socket.io/socket.io.js"></script> <script type="text/javascript" src="<?php echo base_url(); ?>assets/js/uploader.js?a=346456" type="text/javascript" ></script> 

但是，当我然后在我的浏览器中运行我得到未捕获的ReferenceError：需求未定义

任何帮助，请
