錯誤：無法在視圖目錄中查找'socket.io'

Question

我的nodejs服務器有問題。這裏是我的代碼

server.js

global.jQuery = global.$ = require('jquery'); 
var express = require('express'), 
    path = require('path'), 
    menu = require("./routes/menu"); 
var sql = require("mssql"); 
var http = require("http"); 
var io2 = require("io"); 
var app = express(); 


var serve = http.createServer(app); 
var io = require('socket.io')(serve); 

var recordset2; 
var port = 8080; 

app.configure(function() { 
    app.set('views', __dirname + '/views'); 
    app.set('view engine','jade'); 
    /* app.use(express.favicon());*/ 
    app.use(app.router); 
    app.use(express.static(path.join(__dirname+'public'))); 

}); 

app.get('/:viewname', menu.viewname); 



io.on('connection', function (socket) { 
    socket.on('disconnect', function() { 
     console.log('user disconnected'); 
    }); 
    socket.on('chat', function (msg) { 

     socket.broadcast.emit('chat', msg); 
    }); 
}); 

var dbConfig = { 
    server: "localhost", 
    database: "MyDatabase", 
    user: "sa", 
    password: "sa", 
    port: 1433 
}; 

function getConnected() { 
    var conn = new sql.Connection(dbConfig); 
    conn.connect().then(function() { 
     var req = new sql.Request(conn); 
     req.query("SELECT * FROM Countries").then(function (recordset) { 
      console.log("Recordset:", recordset);    
      conn.close(); 
     }).catch(function (err) { 
      console.log("Error!!!!"); 
      console.log(err); 
      conn.close(); 
     }); 
    }).catch(function (err) { 
     console.log("Error!!!! ----"); 
     console.log(err); 
    }); 
} 

getConnected(); 

app.listen(port); 

客戶端的代碼

var socket = io(); 
$(function() { 
    $('#get-button').on('click', function() { 
     console.log("CLICK"); 
     var msg = "HIIII"; 
     socket.emit('chat', msg); 
    }); 
}); 

我試圖使通過套接字服務器和客戶端之間的連接，但它返回我下面的錯誤：

Error: Failed to lookup view 'socket.io' in views directory C:\Radio/views; 
    at Function.app.render (C:\Radio\node_modules\express\lib\application.js:493:17)

    at next (C:\Radio\node_modules\express\node_modules\connect\lib\proto.js:193:15 

你能幫我理解爲什麼嗎？我看到還有另外一個類似的話題，但沒有哪個解決方案有幫助。

發佈此主題後兩分鐘我找到了解決方案。

global.jQuery = global.$ = require('jquery'); 
var express = require('express'), 
path = require('path'), 
menu = require("./routes/menu"); 
var sql = require("mssql"); 
var http = require("http"); 
var io2 = require("io"); 
var app = express(); 
var port = 8080; 
var ser = app.listen(port); //<-----------This solved my problem.
