我用命令express -e ejs microblog,生成的app.js有问题啊。如下是app.js的全部内容。

,/**, * Module dependencies., */,,var express = require('express');,var routes = require('./routes');,var user = require('./routes/user');,var http = require('http');,var path = require('path');,,var app = express();,,// all environments,app.set('port', process.env.PORT || 3000);,app.set('views', __dirname + '/views');,app.set('view engine', 'ejs');,app.use(express.favicon());,app.use(express.logger('dev'));,app.use(express.bodyParser());,app.use(express.methodOverride());,app.use(app.router);,app.use(express.static(path.join(__dirname, 'public')));,,// development only,if ('development' == app.get('env')) {, app.use(express.errorHandler());,},,app.get('/', routes.index);,app.get('/users', user.list);,,http.createServer(app).listen(app.get('port'), function(){, console.log('Express server listening on port ' + app.get('port'));,});,
