我按照教程随手测试了一个例子就报错了，难道作者没测试过吗

看下python报错日志

[Lufffya]

@booboosui 后台并没有看到抛出的错误，你说的是哪个日志？

[booboosui]

服务启动后会有一个python的窗口，里面会显示日志

This error should not affect service operation, is the access to http://127.0.0.1:8080 normal?

Not really. The server spins up eventually, and i get the same errors from the guy above: 'http_proxy' is not recognized as an internal or external command, operable program or batch file. 'https_proxy' is not recognized as an internal or external command, operable program or batch file. 'all_proxy' is not recognized as an internal or external command, operable program or batch file. 000

eventually it will spin up the server Serving HTTP on :: port 8080 (http://[::]:8080/) ... (no ip there, just [::])

So i open http://127.0.0.1:8080/ and it looks like it's not communicating with the backend.

[linussmashtips]

Also: there were errors about HTTP_PROXY, HTTPS_PROXY, ALL_PROXY variable missing, so i set them up in windows environment variables with ip 127.0.0.1:8080

[booboosui]

ALL_PROXY

Is there any error message in the browser console?

hi , you can see local flask version . or you can update watchdog you can try : pip install --upgrade watchdog

[linussmashtips]

ALL_PROXY

Is there any error message in the browser console?

There used to be... CONNECTION_REFUSED i think it was, but @yakeJiang cracked it. it was watchdogs version to blame.

Thank you.
