这个错误目前导致我们对 Airflow 部署产生各种挫败感。我们 运行 气流在 docker 中，奇怪的是，这个问题发生在我自己身上而不是我的同事身上，这使得调试变得非常具有挑战性。我们找到了 ，但是还不是很清楚我们可以做些什么来解决这个错误。
您应该擦除数据库并从头开始重新创建它 (airflow db reset)。显然你的数据库已经损坏 - 如果你使用了一些开发版本的 Arirflow 或 运行 Airflow 2 上的一些旧版本的 airflow 1.10 或相反，这可能会发生。
我想（因为你在谈论 co-worker's 和 your 数据库 - 这些都是开发数据库，所以你应该能够从头开始重置它们。
如果这是一个使用 sqlite 的开发数据库，删除 sqlite3 文件也有帮助（你会在 ${AIRFLOW_HOME} 目录中找到它。这将删除数据库，airflow 将从头开始创建一个启动时自动。
如果卷是通过 docker-compose 创建的，您应该使用 docker-compose down --volumes
