每当我尝试调试python代码时，vscode都会给出一个错误，并通知我调试器的连接被拒绝。我在底部附上了完整的堆栈跟踪
我用的是CentOS 8 Linux。
到目前为止，我已经尝试过：

SELinux关闭
防火墙已禁用
卸载vscode
remove /home/user/.vscode
remove /home/user/.config/Code
清除环境变量

不知道是什么干扰了这里。
我正在调试的文件是print('test')，保存为test.py：-）

我也有同样的问题，经过长时间的研究，我找到了我问题的原因：
1.我的/etc/hosts文件中的localhost不是127.0.0.1
1.因此，DebugAdapter不会侦听地址127.0.0.1
1.因此，“ptvsd --client --host localhost”无法连接到DebugAdapter
解决方案：
在lanuch.json中将主机定义为127.0.0.1

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "host": "127.0.0.1"
        }
    ]
}

在我的情况下是一个完全错误的vscode设置。

创建虚拟环境（我使用venv）
安装VSCode扩展Python
使用以下代码段在项目目录中创建launch.json（并替换为您的信息）

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Flask",
            "type": "python",
            "request": "launch",
            "module": "flask",
            "env": {
                "FLASK_APP": "server.py",
                "FLASK_DEBUG": "1"
            },
            "args": [
                "run",
                "--no-debugger",
                "--no-reload"
            ],
            "jinja": true,
            "justMyCode": true
        }
    ]
}

使用Python: Flask配置运行调试器
