Visual Studio Code Python调试超时。

Question

我正在遵循微软的指南在VS Code中开始使用Python，但只能在调试模式下运行一次 - 接下来的运行将总是遇到超时问题。

这是 hello.py

msg = "Hello World"
print(msg)

这是launch.json文件，基本上只添加了"stopOnEntry": true，因此在调试时会停留在第一行代码处。

    "version": "0.2.0",
    "configurations": [        
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "stopOnEntry": true
        }
    ]
}

我的第一轮调试工作已经完成，Visual Studio Code中的终端显示：

Hello World

然而，如果我再次点击“调试”按钮，它就会卡住，并显示一个错误对话框：

[Open launch.json] [Cancel]

在vscode中，终端显示如下：

发生了什么？ 我该如何解决它？

Answer 1

我通过将终端从“bash”更改为“命令提示符”(cmd)来解决了这个问题。

那怎么做呢？ - Jdeep

当您打开终端控制台时，右上角会出现一个下拉列表，其中列出了您可用的不同终端选项。 - tavito

Answer 2

我在使用微软新安装的Python扩展程序时，也遇到了VS Code的超时问题。我的解决方法是安装插件后立即尝试调试文件，但结果却出现了ConnectionRefusedError。

要解决这个问题，我只需要简单地重新启动VS Code即可。

请定义Python插件，因为有几个选项可用。 - daniboy000
