【问题描述】：
我尝试在 python (python 2.7.10) 中部署一个 Flask 应用程序。 这是一个非常简单的应用程序，带有 requirements.txt
- 烧瓶==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
该应用程序在本地运行。 我现在尝试在 IBM Bluemix 上部署它，并在粘贴命令后
sudo cf push app
sudo cf logs predict_population --recent
我有这个错误：

解决了！而不是写 if name == "main": app.run() 只需做 port = os.getenv('PORT', '5000') if name == "main": app.run(host='0.0.0.0', port=int(port)) 并且有效！
