vscode python 打断点调试配置launch.json

需要直接打开项目工程文件夹，然后点击左侧的蜘蛛按钮然后点击生成launch.json

launch.json

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "my-test-ddp",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "justMyCode": true
        }
    ]
}

然后在需要执行的脚本比如main.py 按F5运行。 但是需要确认一下界面右下脚点击选择执行python的环境

debug一闪而过或者没有任何反应

尝试着vscode的商店里面把python重新安装当前版本的以前年份，比如v2022.8.0。

有时候工作路径不是当前文件目录，需要在.vscode/launch.json添加"cwd": "${workspaceFolder}",
