python - 无法在 Windows 上本地启动气流

问题描述

我一直在尝试在本地 Windows 10 机器上设置 apache-airflow。运行时出现以下错误airflow version，两个 .cfg 文件和缺少 pwd 模块。在过去的 5 天内尝试解决此问题。我还没有使用过venv，但会尝试在venv中安装气流。我安装了 Python 3.8

$ airflow version

Airflow used to look at ~/airflow/airflow.cfg, even when AIRFLOW_HOME was set to a different value. Airflow will now only read C:\Users\[username]\airflow\airflow.cfg, and you should remove the other file

我也尝试过像这样设置系统环境变量。系统环境变量：

解决方案

Airflow 仅适用于类似 Linux 的环境 (Linux/MacOS)。您可以安装在 WSL2（适用于 Linux 2 的 Windows 子系统）中。如果您有兴趣，可以在此处查看一些说明：https ://github.com/apache/airflow/blob/master/BREEZE.rst#docker-in-wsl-2 - 但这些是针对贡献者而非用户的说明。
