I made a simple login system using node and express 4.x. But I write localhost:3000 and see "Not Found 404".I think the problem is the epxress viersion is 4.x,however some code is express 3.x.
This is the error page :
Not Found
404

In your app.js you are loading the routes but you are not telling express to use it. Put app.use('/', routes); right before the 404 catch.
PS: It's the line you've got commented.

This is my file structure:
router.get('/login', function(req, res, next) {
res.render('log_in', { message: null });
req.session.errors = null;
});
As I can see from app.js your express middleware already has /login.
So you need to remove /login from express router;
So your new code should be
router.get('/', function(req, res, next) {
res.render('log_in', { message: null });
req.session.errors = null;
});
I can't seem to get some good feedback to properly diagnose the problem.
Right now I am getting a generic error I set up in the app.js file

The reason your are getting the error is because your exporting a function that takes app and passport as a parameters for your http handlers, but when your require it in your server.js your are not passing passport or app.
You need to somehow pass passport into the require.
You could change your routes files to
If your are using the express.Router
var router = express.Router();
module.exports = function(passport) {
// init your routes with passport and router
router.post('/' function(req, res) {
//...
});
// make sure to return router in the function though
return router;
}
If not using express.Router you could pass both app and passport and simply attach handlers to app
module.exports = function (app, passport) {
app.post('/', function(req, res) {
//...
});
// no need to return app
}
then in server.js
// if your using `express.Router()` in routes file
app.use('/', require('./routes')(passport));
// If your registering handler on app itself just bootstrap it
require('./routes')(app, passport);
You need to pass passport to your route. You can do it changing your code this way:
/routes/index.js
from module.exports = function(app, passport) {...}
to
module.exports = function(passport){ return function(app) {...}}
/server.js
from app.use('/', routes);
to app.use('/', routes(passport));

Do you have any suggestions how I can solve this problem? Help is highly appreciated!
It seems like you are doing a post request and your routes does not have post handler.
May be add route for post:
router.post('/', function(req, res, next) {
//do something and return data here?
});

I used "express mcapp" to create the app....
EDIT app.js code:
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 users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(__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('/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;
