我尝试在OpenShift上部署我的django应用程序，但有些错误，我不知道如何解决这个问题。

这是我第一次在OpenShift（一个PaaS平台）上部署我的应用程序。在此之前，我只使用centos（python3.5，django 1.9.2）在我的CVM上成功部署它。

我的文件是这样的：

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

的myproject / 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

的myproject / myblog / 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由openshift提供。

感谢您关注我的问题并帮助我弄明白。

Answer 1

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

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