Python3.11.5执行pip install pcapy时遇AttributeError错误求助

我执行pip install pcapy命令安装pcapy，持续出现以下错误：

Collecting pcapy

  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

已更新wheel和pip，当前Python版本为3.11.5。

解决方法 #

• 推荐方案：安装兼容Python 3.11的替代包pcapy-ng，执行命令：

  pip install pcapy-ng
  

• 若必须使用原版pcapy，可将Python版本降级至3.10及以下，再执行pip install pcapy
• 不推荐的临时修复：手动修改pcapy源码的setup.py，删除或注释掉引用sysconfig._init_posix的代码，但可能引发其他兼容性问题
