如何无问题地在windows上安装和运行apache-airflow

Question

我试图在windows 10上安装Apache气流2.2.4。当我完成并运行气流时，这里是它给我带来的错误。

下面的步骤为我解决了类似的问题，但不确定是什么解决了它。

1)确保您的wsl版本为2。(如果更改wsl版本，请重新启动PC )

2)为Linux和虚拟机平台启用Windows子系统。(重新启动PC)

在此之后，我遵循了以下教程：https://towardsdatascience.com/run-apache-airflow-on-windows-10-without-docker-3c5754bb98b4

如果您遵循这一点，您将不会安装气流ver1.10.12，但是airflow 2.2.4和而不是"airflow initdb“使用"airflow db init"命令。

此外，在运行命令"airflow db init“之前，要为此创建一个用户，命令(可选，但我建议运行此命令)：

airflow users create --username admin --password admin --firstname <firstname> --lastname <lastname> --role Admin --email abc@gmail.com
