看起来它与高度相关，ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv但不知道如何处理问题。

需要注意的一件事是，当我在本地机器（Mac OS X）上运行完全相同的 dag 而没有任何代码更改（通过airflow dags test my_dag 2021-01-01）时，它运行良好。

我该如何处理这个问题？

解决方案

将选项更改py_system_site_packages为True。它应该使site-packages虚拟环境可见并删除此错误。有关详细说明，请参阅文档。
