地址已在使用中(Errno 98)使用vscode和docker的django

Question

我有一个带有django的python应用程序，我在一个docker容器中运行它。我需要调试这个应用程序，每次我做docker-compose时，它都会在下面给出这个错误。我查看了几个关于如何调试的网站，没有一个解决方案对我有帮助。有人知道它会是什么吗？我认为你需要评估的最重要的文件在下面，如果有更多的需要，我会编辑这篇文章。我使用的是django 2.0.1，ptvsd 3.2.1和Docker-Toolbox。

File "manage.py", line 10, in <module>    ptvsd.enable_attach(secret='my_secret', address = ('192.168.99.100', 3000))
File "/usr/local/lib/python3.6/site-packages/ptvsd/__init__.py", line 87, in enable_attach
return _attach_server().enable_attach(secret, address, certfile, keyfile, redirect_output)
File "/usr/local/lib/python3.6/site-packages/ptvsd/attach_server.py", line 109, in enable_attach
server.bind(address)

要使用自动重新加载功能，您可以使VSCode仅附加到主进程中。基于Django的utils/autoreload.py和Django-Extensions的management/commands/runserver_plus.py：

if os.environ.get('RUN_MAIN') or os.environ.get('WERKZEUG_RUN_MAIN'): ptvsd.enable_attach(address=('0.0.0.0', 7913), redirect_output=True)
