我将 Python 2.7 与 SQLAlchemy 一起使用。我想看看我是否可以使用 Dogpile.Cache。我已经安装了狗堆缓存使用

pip install dogpile.cache

但是当我尝试运行 SQLAlchemy ( helloworld.py ) 给出的示例时，我不断得到ImportError: No module named fcntl。我认为最新的 Dogpile.Cache 解决了 windows 问题...

有人可以帮忙吗？谢谢你。

更新

好的，示例是创建数据库和缓存。但是，当它尝试使用FromCache它加载数据时，会给我一个错误。

people = Session.query(Person).options(FromCache("default")).all()

这是回溯
