c++ - 错误：preLaunchTask 'C/C++:g++.exe build active file' 以退出代码 -1 终止

Question

我是 C++ 和 VS Code 的新手。

我正在尝试使用 g++ 在 VS Code 中调试我的 C++ 代码。

但我收到此错误消息： preLaunchTask 'C/C++:g++.exe build active file' 以退出代码 -1 终止。

这是我的代码：

/*blabla*/

这是我的tasks.json：

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe build active file",
            "command": "C:\\msys64\\usr\\bin\\g++.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "C:\\msys64\\usr\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: C:\\msys64\\usr\\bin\\g++.exe"
        }
    ]
}

这是我的launch.json：

            "name": "g++.exe - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "C:\\msys64\\usr\\bin",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\msys64\\usr\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: g++.exe build active file"
        }
    ]
}

这是我的终端中的内容：

我昨天可以成功调试代码。然后我安装了 git 和 SSH（不确定这是否相关，但包括它以防万一）。

今天，我尝试调试代码，但我无法再成功。

我试图用谷歌搜索错误消息，但无法找出问题所在。
