airflow.exceptions.AirflowConfigException: error: sqlite C library version too old (< 3.15.0). See https://airflow.apache.org/docs/apache-airflow/2.3.2/howto/set-up-database.html#setting-up-a-sqlite-database

原因：

配置文件 airflow.cfg 里面配置项

sql_alchemy_conn = sqlite:////root/airflow/airflow.db

这个配置用到了sqlite

解决办法：规避法

修改配置项

sql_alchemy_conn = mysql://root:123456@localhost:3306/airflow?charset=utf8

其它办法：升级版本
