安装 Apache airflow 时出现的问题

我使用的是 MacOS Mojave、Python 3.8.3 和 pip 23.2。我创建了一个 py_env，激活它，然后运行

pip install apache-airflow==2.6.3' \
 --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.6.3/constraints-3.8.txt".

一开始我遇到一个错误，说找不到文件“pybind11”。我通过运行 python -m pip install pybind11 安装了 pybind11，但现在出现了多个未知类型错误和其他错误。

答案1

我会从最底层的错误开始，然后从那里继续。

ERROR: Could not build wheels for google-re2, which is required to install pyproject.toml-based projects

看来 google-re2 是一个需要满足的约束。

从...开始pip install google-re2 https://pypi.org/project/google-re2/

您还可以前往https://raw.githubusercontent.com/apache/airflow/constraints-2.6.3/constraints-3.8.txt这是成功安装气流所需的软件包列表。

您可以将其与已安装的软件包列表进行比较。您可以通过运行pip list或pip list -v（详细 - 为您提供已安装软件包的位置）来执行此操作
