我尝试在python（python 2.7.10）中部署Flask应用程序。 这是一个非常简单的app.txt应用程序
该应用在本地工作。 我现在尝试在IBM Bluemix上部署它并在粘贴命令
之后sudo cf push app
sudo cf logs predict_population --recent
我有这个错误：

解决了！如果名称==＆＃34;：app.run（），请执行port = os.getenv（＆＃39; PORT＆＃39;，PORT_NUMBER），如果名称==＆＃34;主要＆＃ 34;：app.run（host =＆＃39; 0.0.0.0＆＃39;，port = int（port）），它有效！
