运行从Airflow包导入的python文件，需要airflow实例

我遇到了一个奇怪的进口气流问题.我想创建一个其他人可以从中导入的模块.我还想在此模块上运行单元测试.然而，我注意到，只要你从气流包中导入任何东西，它就会try 运行气流.

示例:

# myfile.py
from airflow import DAG

print("Hello world")

然后用python myfile.py运行它，结果是:

(.venv) c:\Users\Jarro\Development\airflow-tryout-import>python myfile.py
WARNING:root:OSError while attempting to symlink the latest log directory
Traceback (most recent call last):
  File "c:\Users\Jarro\Development\airflow-tryout-import\myfile.py", line 1, in <module>
    from airflow import DAG
  File "C:\Users\Jarro\Development\airflow-tryout-import\.venv\Lib\site-packages\airflow\__init__.py", line 68, in <module>
    settings.initialize()
  File "C:\Users\Jarro\Development\airflow-tryout-import\.venv\Lib\site-packages\airflow\settings.py", line 559, in initialize
    configure_orm()
  File "C:\Users\Jarro\Development\airflow-tryout-import\.venv\Lib\site-packages\airflow\settings.py", line 237, in configure_orm
    raise AirflowConfigException(
airflow.exceptions.AirflowConfigException: Cannot use relative path: `sqlite:///C:\Users\Jarro/airflow/airflow.db` to connect to sqlite. Please use absolute path such as `sqlite:////tmp/airflow.db`.

除了错误本身，我实际上更担心的是，我似乎无法从Airflow导入东西，而没有副作用(如数据库初始化).在这件事上我是不是全错了？有没有其他方法可以从Airflow导入东西，而不会产生这些副作用，例如用于打字？
