Question

我有这个简单的NodeJs代码

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');
})

和两个文件main.handlebars and home.handlebars。但是当我运行此代码时，它会给我以下错误

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

我尝试用res.render('home');替换res.send("works");并且它有效，但我需要包含主页，那么我该怎么办？

Answer 1

express view engine环境变量接受字符串，而不是对象。您可以在

时定义字符串的含义

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

所以，您必须将view engine更改为

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

NodeJS错误：无法找到模块＆＃39; [object Object]＆＃39;
