运行气流时，我一直收到下面的错误？有什么想法吗？一旦我启动气流调度程序，就会发生这种情况。它以前是工作的，但当我更新我的mac时似乎已经停止了。

然后进行以下回溯
The above exception was the direct cause of the following exception:

我曾尝试降级到sqlalchemy的旧版本，但仍然存在相同的问题。我目前使用的版本：1.3.15
试试这个：$airflow initdb
同时检查是否已设置"Airflow Home"。如果initdb不起作用：尝试使用airflow resetdb，但在此之前，如果您有任何数据，请从airflow主目录备份您的DAGS文件夹。
