安装apache-airflow 1.10.5 wheel包出错，求解决方案

我在Python 3.8.12的pyenv环境下，安装包含apache-airflow==1.10.5的requirements.txt时遇到错误。已经尝试过升级setuptools、安装并升级apispec、升级pip（受限于pyenv绑定版本），求下一步解决方法。

解决步骤 #

• 锁定Flask-AppBuilder兼容版本：错误根源是Flask-AppBuilder 1.13.1的依赖写法apispec[yaml]>=1.1.1<2不符合新版pip/setuptools的语法规范。手动安装修复了该问题的1.13.0版本，再安装Airflow：

  pip install "Flask-AppBuilder==1.13.0" "apache-airflow==1.10.5"
  

• 回退setuptools版本：新版setuptools对依赖语法校验更严格，回退到兼容的旧版本（如45.x系列）：

  pip install setuptools==45.0.0
  pip install "apache-airflow==1.10.5"
  

• 启用旧版依赖解析器：让pip使用legacy-resolver模式，兼容不规范的依赖写法：

  pip install "apache-airflow==1.10.5" --use-deprecated=legacy-resolver
