【问题描述】：

我是 Visual Code 的新手。我想将调试功能与可视代码一起使用。但是有一个问题可以做到。错误的launch.json设置可能会发生（在我的选择中）

我正在使用 mac os 最新版本。

我自己参考了一些页面。

https://code.visualstudio.com/docs/languages/cpp

https://github.com/Microsoft/vscode-cpptools/blob/master/launch.md

https://code.visualstudio.com/docs/python/debugging

但是我看到了同样的错误。它说“启动：程序 '${/Users/bpk/Documents/Study/C/Study}/study' 不存在”

这是我下面的 launch.json 文件

    {
    "version": "0.2.0",
    "configurations": [

{
    "name": "Python3",
    "type": "python",
    "request": "launch",
    "stopOnEntry": true,
    "pythonPath": "${config:python.pythonPath}",
    "program": "${/Users/bpk/Documents/Study/Python3/study.py}",
    "cwd": "${/Users/bpk/Documents/Study/Python3}",
    "env": {},
    "envFile": "${/Users/bpk/Documents/Study/Python3}/.env",
    "debugOptions": [
        "RedirectOutput"
    ]
},
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${/Users/bpk/Documents/Study/C/Study}/study",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${/Users/bpk/Documents/Study/C/Study}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        },
        { 
            "name": "(gdb) Attach",
            "type": "cppdbg",
            "request": "attach",
            "program": "${/Users/bpk/Documents/Study/C/Study}/study",
            "processId": "${command:pickProcess}",
            "MIMode": "gdb"
        }
    ],
    "compounds": []
}

【解决方案1】：

我认为您混淆了变量和字符串 ${...} 表示在可视代码中使用的变量。目录路径不需要包含 ${}。

您的 Python3 配置应如下所示：

{
    "name": "Python3",
    "type": "python",
    "request": "launch",
    "stopOnEntry": true,
    "pythonPath": "${config:python.pythonPath}",
    "program": "/Users/bpk/Documents/Study/Python3/study.py",
    "cwd": "/Users/bpk/Documents/Study/Python3",
    "env": {},
    "envFile": "/Users/bpk/Documents/Study/Python3/.env",
    "debugOptions": [
        "RedirectOutput"
    ]
},

对 C 调试配置的更改与 Python 大致相同，应如下所示：

 {
     "name": "(gdb) Launch",
     "type": "cppdbg",
     "request": "launch",
     "program": "/Users/bpk/Documents/Study/C/Study/study",
     "args": [],
     "stopAtEntry": false,
     "cwd": "/Users/bpk/Documents/Study/C/Study",
     "environment": [],
     "externalConsole": false,
     "MIMode": "gdb",
     "setupCommands": [
         {
             "description": "Enable pretty-printing for gdb",
             "text": "-enable-pretty-printing",
             "ignoreFailures": true
         }
     ]
 },
