的NodeJS錯誤：無法找到模塊「的翻譯：」

Question

我有這個簡單的NodeJS代碼

var express = require('express'), 
    app = express(); 


app.disable('x-powered-by'); 

var handleBars = require('express-handlebars').create({defaultLayout:'main'}); 

app.engine('handlebars',handleBars.engine); 
app.set('view engine',handleBars); 

app.set('port',process.env.PORT || 3000); 

app.get('/',function(req,res){ 
    res.render('home'); 
}) 

app.listen(app.get('port'),function(){ 
    console.log('Working boy'); 
}) 

和兩個文件main.handlebars and home.handlebars。但是當我運行這段代碼是給了我這個以下錯誤

Error: Cannot find module '[object Object]' 
    at Function.Module._resolveFilename (module.js:469:15) 
    at Function.Module._load (module.js:417:25) 
    at Module.require (module.js:497:17)

    at next (/Users/muradshahmammadli/Desktop/progr/NodeJS/node_modules/express/lib/router/route.js:137:13) 

我試圖用res.send("works");替換res.render('home');，它工作，但我需要包括主頁，所以我能做什麼？

快遞view engine環境變量接受一個字符串，而不是一個對象。您可以定義當你做

app.engine('handlebars', handleBars.engine); 

有啥字符串意味着，你必須改變你view engine到

app.set('view engine', 'handlebars');
