在Openshift中使用Flask_Restful时出错

我正在尝试使用Flask restful创建openshift应用程序。我可以按照openshift website中的说明安装我的应用程序。但除此之外，我想使用flask_restful。在Openshift中使用Flask_Restful时出错

所以我创建了一个的virtualenv和点子安装flask_restful。然后使用Flask_restful网站中的example，我复制了示例代码并将其粘贴到flaskapp.py中（请参阅openshift example）。我也加了Flask-RESTful == 0.3.5在requirements.txt。

然后我就能够运行python wsgi.py，它在我的机器上成功运行在本地。我能够得到我期待的结果。我有点期待当我将这些改变推向openshift时，它会顺利运行。但它没有给我一个500内部服务器错误消息。

为了给你一个想法，这里是我的一些文件

requirements.txt

Flask==0.10.1 
Flask-RESTful==0.3.5:

flaskapp.py

from flask import Flask 
from flask_restful import Resource, Api 

app = Flask(__name__) 
api = Api(app) 

class HelloWorld(Resource): 
    def get(self): 
     return {'hello': 'world'} 

api.add_resource(HelloWorld, '/') 

if __name__ == '__main__': 
    app.run(debug=True)

wsgi.py

#!/usr/bin/python 
import os 

#virtenv = os.environ['OPENSHIFT_PYTHON_DIR'] + '/virtenv/' 
virtenv = os.path.join(os.environ.get('OPENSHIFT_PYTHON_DIR','.'), 'virtenv') 
virtualenv = os.path.join(virtenv, 'bin/activate_this.py') 
try: 
    execfile(virtualenv, dict(__file__=virtualenv)) 
except IOError: 
    pass 
# 
# IMPORTANT: Put any additional includes below this line. If placed above this 
# line, it's possible required libraries won't be in your searchable path 
# 
from flaskapp import app as application 

# 
# Below for testing only 
# 
if __name__ == '__main__': 
    from wsgiref.simple_server import make_server 
    httpd = make_server('localhost', 8051, application) 
    # Wait for a single request, serve it and quit. 
    #httpd.handle_request() 
    httpd.serve_forever()

什么错误信息是在日志？ –

我将日志添加到问题中。 – Lance

它说没有名为烧瓶的模块。在我的require.txt或virtualenv中有什么不对吗？ – Lance

终于想通了。我需要添加flask_restful到的setup.py

setup.py

from setuptools import setup 

setup(name='YourAppName', 
     version='1.0', 
     description='OpenShift App', 
     author='Lance', 
     author_email='[email protected]', 
     url='http://www.python.org/sigs/distutils-sig/', 
     install_requires=['flask_restful'], 
    )
