python之Openshift 上的 Django之500 内部服务器错误之wsgi.py 中的错误

我试图在 OpenShift 上部署我的 django 应用程序，但出了点问题，我不知道如何解决这个问题。

rhc tail -a myproject 的结果: (并且站点页面显示 500 Internal Server Error)

这是我第一次在 PaaS 平台 OpenShift 上部署我的应用程序。 在此之前，我只是用centos(python3.5, django 1.9.2)在我的CVM上部署成功。

我的文件是这样放的:

myproject/ 
+---wsgi/ 
|   +---static/ 
|       +---.gitkeep 
+---wsgi.py 
+---setup.py 
+---.openshift/  
+---requirements.txt 
+---myblog/ 
|   +----__init__.py 
|   +----urls.py 
|   +----settings.py 
|   +----wsgi.py 
+---+blog/ 
    +----__init__.py 
    +----models.py 
    +----views.py 
    +----tests.py 
    +----migrations 
         +---__init__.py 

我的项目/wsgi.py:

#!/usr/bin/python 
import os 
virtenv = os.environ['OPENSHIFT_PYTHON_DIR'] + '/virtenv/' 
virtualenv = os.path.join(virtenv, 'bin/activate_this.py') 
try: 
    exec(compile(open(virtualenv, 'rb').read(), virtualenv, 'exec'), dict(__file__=virtualenv)) 
except IOError: 
    pass 
 
from myblog.wsgi import application 

我的项目/我的博客/wsgi.py:

import os 
from django.core.wsgi import get_wsgi_application 
 
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myblog.settings") 
application = get_wsgi_application() 

我的Django版本是最新的1.9.2，python 3.3是openshift提供的。

感谢您关注我的问题并帮助我解决问题。

请您参考如下方法:

仅限 Django 1.9 supports Python 3.4 or higher .您的特定错误是由调用 find_spec 引起的 added in Python 3.4 .

您可以降级到 Django 1.8 或选择其他支持 Python 3.4 的 PaaS 提供商。
