python - OSError: [WinError 10013] 试图以访问权限禁止的方式访问套接字

问题描述

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（我正在使用 Windows）。我已经按照更新的自述文件进行了操作，并设法让所有三个窗口都正常运行。但是当我打开http://localhost:6060/

我单击发送按钮，这会破坏 Huey_consumer 进程：

我怎样才能得到这个工作？

解决方案

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，在我的例子中是端口 8097。

为了调试它，我按照以下步骤操作：

  1. 使用Sysinternals 的 TcpView来查找使用端口的进程。
  2. 如果进程结果是 svchost.exe，那么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.
  3. 打开 Windows 服务小程序并查找此服务器。在我的情况下，这被证明是“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端口。
