在 Visual Studio 代码中调试（C++ 程序）时看不到矢量或其他容器（例如地图）的内容

Question

我编写了一个简单的 C++(11) 程序来测试 Windows 中 Visual studio 代码中的调试器。我正在使用 MinGW 发行版作为编译器选项。我已经按照此处的文档设置了 tasks.json 和 launch.json： https://code.visualstudio.com/docs/cpp/config-mingw

这里是示例 cpp 代码：

typedef std::vector<int> vi;    
int main(int argc, char const *argv[])
{
    fast();
    int tests = 1;
    cin >> tests;
    while(tests--)
    {
        int n = 5, k = 25;
        cin >> n >> k;
        vi permutation(n);
        for (int i = 0; i < n; i++)
        {
            cin >> permutation[i];
        }

        // vi permutation = {5,4,3,2,1};
        auto ans = solve(permutation, k);
       // other logic goes here

    }
    return 0;
}

我的 tasks.json 文件：

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "C/C++: g++.exe build active file",
            "command": "C:\MinGW\bin\g++.exe",
            "args": [
                "-g",
                "-std=c++11",
                "${file}",
                "-o",
                "${fileDirname}\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "C:\MinGW\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "echo": false,
                "reveal": "always",
                "focus": true,
                "panel": "shared",
                "clear": false,
                "showReuseMessage": false
            },
        }
    ]
}

我的launch.json文件：

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

我在调试器中看到了这个 window：

根据文档，我应该会看到如下所示的屏幕：

我是不是设置错了？为什么我看不到容器的内容？我观察到我也看不到其他容器的值。

我从您提到的站点安装 MINGW 时遇到了同样的问题。然后我从 SourceForge mentioned in the wiki 安装了 MINGW，它开始工作正常。请试一试。
