我安装了python_beaker，将其添加到include：
session_factory = session_factory_from_settings(settings)
config = Configurator(settings=settings, session_factory=session_factory)
config.include('pyramid_beaker')
将这些设置添加到development.ini中：
session.type = file
session.data_dir = /tmp/sessions/data
session.lock_dir = /tmp/sessions/lock
session.key = key
session.secret = secret
session.cookie_on_exception = true
但会议永远不会结束。我做错了什么？
