我使用的是 MacOS Mojave、Python 3.8.3 和 pip 23.2。\n我创建了一个 py_env，激活它，然后运行
\npip install apache-airflow==2.6.3' \\\n --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.6.3/constraints-3.8.txt".\n起初我遇到一个错误，说找不到文件“pybind11”。我通过运行 python -m pip install pybind11 安装了 pybind11，但现在出现多个未知类型错误和其他错误。
