python - 操作系统错误 : [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

Question

我正在尝试使用 Huey 作为跨平台任务队列。我找到了 https://github.com/pjcunningham/flask-huey-example ，我已经克隆并设置了一个用于使用 conda 的 virtualenv(我在 Windows 上工作)。我遵循了更新的自述文件，并设法让所有三个窗口都正常运行。但是，当我打开 http://localhost:6060/ 时

我点击发送按钮，这打破了 Huey_consumer 过程:

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

我怎样才能让它工作？

Answer 1

尝试启动 Visdom 服务器时出现完全相同的错误:

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

原因是有另一个进程使用与 Visdom 想要使用的端口相同的端口，在我的情况下是端口 8097。

为了调试这个，我遵循了以下步骤:

使用 TcpView from Sysinternals使用端口查找进程。

如果该进程是 svchost.exe，则您需要找到使用此端口的服务。为此，请运行以下命令:`tasklist/svc/FI "PID eq 1234"where replce 1234 from PID you see in TcpView.

打开 Windows 服务小程序并查找此服务器。在我的情况下，结果是“交付优化”或 DOSvc 服务，如果您在大型网络上，它基本上使用 Windows 更新位的 P2P 下载。我暂时关闭了该服务并能够再次打开该端口。
