AttributeError: module 'socket' has no attribute 'SO_REUSEPORT'. sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)

python应用运行报错，部分错误信息如下：

问题出在vLLM服务器启动时尝试使用 SO_REUSEPORT 套接字选项，该选项在 Windows 平台上不可用。提示信息如：AttributeError: module ‘socket’ has no attribute ‘SO_REUSEPORT’. Did you mean: ‘SO_REUSEADDR’?

解决方法

直接注释掉下面这行代码

sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)

改为使用

sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
