C++：為什么我無法打開具有相對路徑的文件？

Question

以前用Visual Studio 2019開發C和C++程序，現在轉到VS Code，調試的時候發現不能用相對路徑打開文件，只能用絕對路徑才能工作。

這是我的 launch.json 和 tasks.json 文件：

發射.json：

{
    // 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": "gcc.exe - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "C:\\mingw64\\bin",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\mingw64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: gcc.exe build active file"
        }
    ]
}

任務.json：

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: gcc.exe build active file",
            "command": "C:\\mingw64\\bin\\gcc.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "C:\\mingw64\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

非常感謝你解決了我的問題。

從應用程序的當前工作目錄遇到相對路徑，並且您已提供

"cwd": "C:\\mingw64\\bin",

如果您想從當前項目根目錄運行，請將其設置為這樣（或將其設置為您喜歡的位置）

"cwd": "${workspaceRoot}"

編輯：如果您以這種方式設置它以便能夠運行gcc考慮在您的 PATH 變量中添加C:\\mingw64\\bin 。
