使用PyDBLite的Flask-RESTful API在WSGI中失败

如何解决使用PyDBLite的Flask-RESTful API在WSGI中失败

摘要：
我为内存数据库使用PyDbLite创建了一个使用Flask-RESTful的超级简单API。当运行'python api.py'时，它工作得很好。但是，当我将其放入apache2 wsgi中时，它开始失败：

getitem 中的文件“ /usr/local/lib/python2.7/dist-packages/pydblite/pydblite.py”，第471行 返回self.records [key] AttributeError：“ _ BasePy2”对象没有属性“ records”

详细信息： 主应用程序：/var/www/api/api.py
