【问题描述】：
我刚刚安装了 Airflow 并使用外部触发器（播放按钮）选项运行了一个示例 DAG。当我转到 DagRuns 选项时，我收到以下异常。几年前我使用过 Airflow，所以我不确定现在出了什么问题。我也在页面顶部注意到了这一点
调度程序似乎没有运行。
DAG 列表可能不会更新，并且不会安排新任务。
虽然它正在运行。

【问题讨论】：
-
这似乎是与操作系统相关的问题。根据您的操作系统，您可以尝试
export LC_ALL=en_US.UTF-8\ export LANG=en_US.UTF-8。 -
@mad_ 已经做没有改变
-
您使用的是什么操作系统？您还提到调度程序没有运行。你知道为什么吗？
-
不，我不知道为什么它说运行时不运行！我正在使用 MacoS Catalina
-
这能回答你的问题吗？ stackoverflow.com/questions/19961239/…
