Question

我是气流的新手，我只是按照教程进行操作。实际上我确实成功完成了，但是问题是当我尝试通过输入airflow pause dag_id之类的命令行来暂停dag时，它会抛出AttributeError: 'NoneType' object has no attribute 'is_paused'

回溯为：

File "/anaconda3/bin/airflow", line 32, in <module>
    args.func(args)
  File "/anaconda3/lib/python3.6/site-packages/airflow/utils/cli.py", line 74, in wrapper
    return f(*args, **kwargs)
  File "/anaconda3/lib/python3.6/site-packages/airflow/bin/cli.py", line 365, in pause
    set_is_paused(True, args, dag)
  File "/anaconda3/lib/python3.6/site-packages/airflow/bin/cli.py", line 379, in set_is_paused
    dm.is_paused = is_paused

所以我检查了输出目录中的python文件，但是，它是由airflow编码的，我不知道该如何解决？！！

Answer 1

这可能是因为DAG（tutorial.py）不在气流期望DAG所在的目录中。请检查DAG是否存储在dags_folder下airflow.cfg中设置的目录中。

Answer 2

如果您正在使用该代码段读取任何文件，请确保包括完整路径。相对路径不起作用。

气流“ NoneType”对象没有属性“ is_paused”，如何解决？
