“错误：没有默认引擎指定并没有扩展名被提供”，用特快车把

var express = require('express');  
var exphbs = require('express-handlebars');  
var MailerConnect = require('./nodemailer.js');  
var app = express();  
app.engine('handlebars', exphbs({  
    defaultLayout: 'test'  
}));  
app.set('view engine', 'handlebars');  
var file = module.exports = {  
    Mailer: function(req, res) {  
    res.render('testtemplate', function(err, data) {  
     var data = data;  
     console.log(data);  
     MailerConnect.sendMail(data);  
    });  
    }  
}

Error: No default engine was specified and no extension was provided. at new View (C:\Users\manjunathan\node_modules\express\lib\view.js:61:11) at Function.render (C:\Users\manjunathan\node_modules\express\lib\applicatio n.js:570:12) at ServerResponse.render (C:\Users\manjunathan\node_modules\express\lib\resp onse.js:1008:7) at Object.Mailer (C:\Users\manjunathan\app.js:13:7)]

回答：

app.set('views', path.join(__dirname, 'views'));
