Displaying views in Node.js/Express

I am following the peepcode (part 1) video tutorial on node.js, and I am getting stuck on the first few steps. When I try to go to http://localhost:3000/login, I get the following error:

500 Error: Failed to lookup view "/Users/dantang/Desktop/Programming/Node/basic server/hotpie/apps/authentication/views/login"

I'm guessing it is due to a typo, but I've tried changing the code several times and I can't figure out what is wrong. Would really appreciate it if someone could tell me what should I do? Thank you!

require("coffee-script");

var express = require('express')
  , http = require('http')
  , path = require('path');

var app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());

  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

app.configure('development', function(){
  app.use(express.errorHandler());
});


//Routes
require('./apps/authentication/routes')(app);


http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});

login.jade

form(action='/sessions', method='post')
  label
    | Username
    input(type='text', name='user')

routes = (app) ->

  app.get '/login', (req, res) ->
    res.render "#{__dirname}/views/login",
      title: 'Login'

module.exports = routes
