气流安装问题|设置标题

Question

我已按照以下步骤安装 airflow 并已成功安装，但无法运行任何以 airflow 开头的命令，甚至无法检查版本。感谢任何帮助。

python3.9 -m venv airflowenv ,
来源 airflowenv/bin/activate 导出 , AIRFLOW_HOME=~/气流, 回声 $AIRFLOW_HOME ,

pip 安装 --upgrade pip , pip 安装 apache-airflow==1.10.15 , 气流 initdb.

这是我收到的错误：

Answer 1

您应该在安装 Airflow 时使用约束。请参阅此 link 解释原因：https://airflow.apache.org/docs/apache-airflow/stable/installation.html#constraints-files

在您的情况下，正确的命令是：

pip install apache-airflow==1.10.15 --constraint https://raw.githubusercontent.com/apache/airflow/constraints-1.10.15/constraints-3.8.txt

Answer 2

如果您使用的是 MacOS，则需要按照 https://www.python.org/downloads/.

手动安装 Python 3.8
