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应用程序与requirements.txt
- 瓶= = 0.10.1
- 分发= = 0.6.27
- setuptools = = 20.3
- scipy = = 0.17
- matplotlib = = 1.5.1
- pickleshare = = 0.7.2
- scikit-learn = = 0.17.1
- numpy = = 1.11.1
应用程序在本地工作。现在我尝试在IBM Bluemix上部署它，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!而不是写if name == "main": app.run()只是做port = os。gettenv ('PORT'， PORT_NUMBER)如果name == "main": app.run(host='0.0.0.0'， PORT =int(PORT))，它就可以工作了!
