VS Code Python调试执行代码时出现“ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接”的问题解决

问题描述

配置好VS Code环境，安装好Python extension for Visual Studio Code，设置好代码的断点，进行调试执行，出现以下错误：

sock.connect((host, port))
ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接。

同时还会出现一个对话框，上面写着“time out”之类的话语。

解决方法

设置网络连接的属性。如下图所示：

更改好上述设置后，再次调试执行，能正常用了，如下图所示：

讨论

VS Code 确实是一个好用的IDE。在用的过程中会出现一些问题，需要解决。后面，我又把上面设置改回原来的设置值，调试也能正常执行，这非常奇怪。不过，多用用，多积累经验吧！
