Question

我正在尝试将我的应用程序部署到Heroku。

构建成功但存在应用程序错误。

这是构建日志：

2017-08-19T10:52:32.433135+00:00 heroku[web.1]: State changed from crashed to

MongoClient.connect with auth credentials.

真的希望有人能指出我正确的方向。感谢。

在这里为我找到解决方案：Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

在我的情况下，我的应用程序崩溃，因为我很难设置PORT，而不是使用heroku dinamicaly设置的端口，可以使用process.env.PORT访问

 app.listen(process.env.PORT || 3000, function(){
 console.log("Express server listening on port %d in %s mode", 
 this.address().port, app.settings.env);
 });

部署到Heroku时失败
