python - python socket.error: [Errno 98] 地址已在使用中

Question

当我设置 application.py 时，它显示 socket.error: [Errno 98] 地址已在使用中。

Traceback (most recent call last):
File "application.py", line 121, in <module>
main()
File "application.py", line 117, in main
http_server.listen(options.port)

Answer 1

显然有另一个进程正在侦听该端口。您可以使用以下命令找出该过程：

$ lsof -i :8000

或更改您的龙卷风应用程序的端口。龙卷风的错误信息没有明确说明。
