问题解决了，是因为有个用bottle启动的web程序占用了8000端口，而SimpleHTTOServer默认也是8000端口

Address already in use means that you have another Python HTTP server running on the machine

[wsw70]

@gabfl yes, or any other service which binds to that specific port

[gabfl]

correct, indeed

[wsw70]

@DamonDBT you have something running on the default port used by the built-in Python web server (namely 8080). Try to start your server with

python -m SimpleHTTPServer 9977

For python 3.x this would be

python -m http.server 9977

or

python3 -m http.server 9977

Your site will the be at http://localhost:9977. You can use any other port not used by another service.
