How do I use C++20 in vscode?（3个答案）
How to enable C17 support in VSCode C Extension（8个答案）
2天前关闭。
我尝试用C++中的括号初始化一个map，如下所示：

const unordered_map <int, int> prova = 
    {
        {0,1},
        {4,2}
    };

如果我在VSCode上编译，我会一直得到error: non-aggregate type 'const unordered_map<int, int>' cannot be initialized with an initializer list。
我在编译器参数配置字段中包含了-std=c++20，并尝试了g++/clang/clang++/gcc等的每种组合，得到了相同的结果。
当我从终端编译时，使用g++ -std=c++20 -o prova prova.cpp时一切都很好，除非我省略了参数-std=c++20，在这种情况下，我会得到与上面相同的错误。
我不得不承认我对c++的了解非常有限。据我所知，我的系统是最新的。g++ —-version的完整输出如下

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1 Apple clang version 13.0.0 (clang-1300.0.29.30) Target: x86_64-apple-darwin20.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

.vscode/settings.json文件为空，而.vscode/c_cpp_properties.json看起来如下所示：

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/g++",
            "cStandard": "c17",
            "cppStandard": "c++20",
            "intelliSenseMode": "macos-clang-x64",
            "compilerArgs": [
                "-std=c++20"
            ]
        }
    ],
    "version": 4
}

这是.vscode/tasks.json：

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: clang++ compila il file attivo",
            "command": "/usr/bin/clang++",
            "args": [
                "-fcolor-diagnostics",
                "-fansi-escape-codes",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Attività generata dal debugger."
        }
    ],
    "version": "2.0.0"
}

您是否知道导致此问题的原因以及解决方法？
