路由器的代码： //about.js

var express = require('express'); 
var router = express.Router(); 

router.get('/about', function(req, res, next) { 
    console.log("/about route"); 
    res.render('about', { title:'About',name:'Praveen' }); 
}); 

module.exports = router; 

//app.js代码

var express = require('express'); 
var path = require('path'); 
var favicon = require('serve-favicon'); 
var logger = require('morgan'); 
var cookieParser = require('cookie-parser'); 
var bodyParser = require('body-parser'); 

var routes = require('./routes/index'); 
var about = require('./routes/about'); 
//var users = require('./routes/users'); 

var app = express(); 

// view engine setup 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'ejs'); 

// uncomment after placing your favicon in /public 
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); 
app.use(logger('dev')); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: false })); 
app.use(cookieParser()); 
app.use(express.static(path.join(__dirname, 'public'))); 

app.use('/', routes); 
app.use('/about', about); 

//app.use('/users', users); 

// catch 404 and forward to error handler 
app.use(function(req, res, next) { 
    var err = new Error('Not Found'); 
    err.status = 404; 
    next(err); 
}); 

// error handlers 

// development error handler 
// will print stacktrace 
if (app.get('env') === 'development') { 
    app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
     message: err.message, 
     error: err 
    }); 
    }); 
} 

// production error handler 
// no stacktraces leaked to user 
app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
    message: err.message, 
    error: {} 
    }); 
}); 


module.exports = app;

我得到上面的错误，如果我试图在我的节点应用程序访问不同的路线。请帮助

这里的问题是，在有关文件的路径实际上是被解析为/about/about。如果您尝试打开该网址，它应该可以正常工作。

这是因为在app.js，你说，所以在about.js所有路由已经与​​启动“前进，随着/即将about.js开始的所有请求”：app.use('/about', about);

要解决这个问题，只需更新在about.js的路线：

router.get('/', function(req, res, next) {
