如何在Visual Studio代码中使用特定的可靠版本进行编译？

# 例如，安装GCC 9.x版本
sudo apt update
sudo apt install gcc-9 g++-9

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "/usr/bin/gcc-9 -g ${file} -o ${fileDirname}/${fileBasenameNoExtension}",
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": [
                "$gcc"
            ]
        }
    ]
}

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "gcc ${file} -o ${fileDirname}/${fileBasenameNoExtension}",
            "options": {
                "env": {
                    "CC": "/usr/bin/gcc-9",
                    "CXX": "/usr/bin/g++-9"
                }
            },
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": [
                "$gcc"
            ]
        }
    ]
}

export CC=/usr/bin/gcc-9
export CXX=/usr/bin/g++-9
gcc ${file} -o ${fileDirname}/${fileBasenameNoExtension}
