Django WSGI 部署。无法导入名称 'SimpleCookie'
Django WSGI deployment. cannot import name 'SimpleCookie'
我正在尝试部署 Django 站点。它按预期在开发服务器中运行。
运行 python 在cp虚拟环境下也导入成功
但是在 Apache mod_wsgi 下，我得到了站点的以下错误日志：

我的 wsgi.py 文件是：

编辑：
我不完全明白为什么，但是当删除
sys.path.insert(0, '/var/www/.virtualenvs/cp/lib/python3.4/site-packages/django')
一个错误改成另一个：
django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named '_sqlite3'
似乎这解决了原来的错误，但引发了一个新错误。
编辑2：
我试着添加

在调用get_wsgi_application()之前，但这并不能解决_sqlite3导入错误
关闭此问题并为新错误打开一个新问题：
