升级Python至3.12.3后安装socketio遇netifaces编译失败求助

问题现象 #

之前用Python 3.12.2安装socketio后项目运行正常，升级到Python 3.12.3后安装socketio时触发编译错误，具体报错如下：

Creating library build\temp.win-amd64-cpython-312\Release\netifaces.cp312-win_amd64.lib and object build\temp.win-amd64-cpython-312\Release\netifaces.cp312-win_amd64.exp
netifaces.obj : error LNK2001: unresolved external symbol PyUnicode_FromUnicode
build\lib.win-amd64-cpython-312\netifaces.cp312-win_amd64.pyd : fatal error LNK1120: 1 unresolved externals
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2022\\BuildTools\\VC\\Tools\\MSVC\\14.39.33519\\bin\\HostX86\\x64\\link.exe' failed with exit code 1120
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for netifaces
Failed to build netifaces
ERROR: Could not build wheels for netifaces, which is required to install pyproject.toml-based projects

本质是netifaces源码编译时找不到Python 3.12.3中被移除的PyUnicode_FromUnicode符号，导致wheel构建失败，进而卡住socketio的安装流程。

解决办法 #

• 强制安装预编译二进制包：跳过源码编译环节，直接让pip拉取适配Python 3.12.3的预编译netifaces包，执行命令：

  pip install netifaces --only-binary :all:
  

  装完netifaces后再正常安装socketio即可。

• 回退Python版本：暂时降级到Python 3.12.2，这个版本能正常编译netifaces，适配socketio的安装需求。

• 更新netifaces到最新版：执行命令升级netifaces，新版本大概率修复了Python 3.12.3的兼容性问题：

  pip install --upgrade netifaces
