Question

研究一些气流监测的想法。当我执行airflow list_tasks my_dag时，会得到大量不必要的垃圾以及实际的期望输出：

[2018-12-11 22:39:00,301] {__init__.py:51} INFO - Using executor SequentialExecutor

SyntaxError: invalid syntax
also_run_this
run_after_loop
run_this_last
runme_0
runme_1
runme_2

我真正需要的是：

also_run_this

run_after_loop

run_this_last

runme_0

runme_1

runme_2

除了实际结果之外，是否有一种方法可以抑制所有情况？

Answer 1

将韧性升级到最新版本虽然在升级时，它显示警告： “ apache-airflow 1.10.1要求韧度== 4.8.0，但您将具有不相容的韧度5.0.2”。请忽略此

兼容性：的Python 3.7.1 apache-airflow 1.10.1 韧性5.0.2

希望这会有所帮助！

Answer 2

您使用的Python版本将async视为保留字。您可以降级到不是这种情况的版本，或者可以在配置中禁用示例DAG。
