Apache Airflow - Python 能力问题

Question

As per the most recent release of Apache Airflow, Airflow 2.0+, and its upgrading documentation found here , Python 3.9 is not supported. However, my understanding is that Python 3.9 is not supported for running Apache Airflow, but what about.py files, scripts, etc. written in and libs, modules, etc. built upon Python 3.9?

Can I download Python 3.8 to run Apache Airflow, and via the Bash Operators run Python files that operate on Python 3.9?

Answer 1

您可以使用PythonVirtualenvOperator在您想要的任何版本中运行 python 代码。 该运算符具有可以设置的python_version参数。

例子：

virtualenv_task = PythonVirtualenvOperator(
    task_id="virtualenv_python",
    python_callable=callable_virtualenv,
    requirements=["requests==2.25.0"],
    system_site_packages=False,
    python_version="2.7" # set to the version you'd like.
    dag=dag,
)
