javascript-Node.js应用程序,Express和Cloud Foundry

我正在使用开箱即用的expressjs应用程序,并且正在使用节点0.8.2.在本地运行良好,但是当我推送到Cloud Foundry时,出现以下错误,并且我不知道从哪里开始调试.我假设这是由配置问题或依赖性问题引起的,但我不知道该怎么办.

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

解决方法:

看来此问题是由连接(表达的依赖项)引起的.我最初使用在节点0.8.8上运行的express创建了我的应用,而CF使用的是0.8.2.即使我在本地似乎没有什么不同,但是当我部署到Cloud Foundry时却遇到了此错误.

我创建了一个全新的应用程序,从一开始就运行Node 0.8.2.这似乎解决了这个问题.
