我是Python（以及GAE）的新手，我正在尝试将gaesessions包含在我的应用程序中，这正是我所做的：
我将gaesessions文件夹复制到我的src文件夹（该文件夹包含__init__.py文件）
并将其添加到我的工作代码中：
from gaesessions import get_current_session
session = get_current_session()
我收到以下错误：

答案 0 :(得分：7)
你已经从堆栈跟踪中省略了实际的异常，但我猜是这样的：
AttributeError：'local'对象没有属性'current_session'
如果是这样，您很可能会跳过middleware configuration步骤。根据说明创建appengine_config.py并重新启动开发服务器;这应该可以解决你的错误。
