Airflow Web 服务器没有名为“airflow.www.fab_security”的模块

Question

我在 Ubuntu 上运行 Airflow 1.10.12。使用本地执行器和 MySql，Airflow 运行良好。为了进行一些测试，我已经使用 RabbitMQ 迁移到 Celery 执行器。基于教程，这是我的配置文件：

[core]
executor = CeleryExecutor
[celery]
broker_url = pyamqp://rabbitmq:rabbitmq@localhost/
result_backend = db+mysql+pymysql://airflow:airflow@localhost:3306/airflow_db

但是当我跑步时：

airflow webserver

抛出以下错误：
