安装构建工具后未找到 Visual Studio Code MSVC cl.exe

Question

设置 VS Code 后，安装构建工具并在此处完成教程：https : //code.visualstudio.com/docs/cpp/config-msvc

Visual Studio Code 无法找到用于编译 C++ 的 cl.exe。

我用硬盘驱动器上的正确路径替换了教程中的路径（cl.exe 在那里）。

// My Config
{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.17763.0",
            "compilerPath": "C:/Program Files (x86)/Microsoft Visual Studio/2019/BuildTools/VC/Tools/MSVC/14.22.27905/bin/Hostx64/x64/cl.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "msvc-x64"
        }
    ],
    "version": 4
}

// The tutorial build-task
{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "msvc build",
            "type": "shell",
            "command": "cl.exe",
            "args": [
                "/EHsc",
                "/Zi",
                "/Fe:",
                "helloworld.exe",
                "helloworld.cpp"
            ],
            "group":  {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "reveal":"always"
            },
            "problemMatcher": "$msCompile"
        }
    ]
}

运行构建任务时会显示此错误，尽管compilerPath正确（cl.exe 在那里）并且 helloworld.cpp 也存在。以管理员身份运行一切都没有帮助。

}

'c_cpp_properties.json' 文件仅在 C/C++ 扩展中配置 IntelliSense，因此该compilerPath选项对构建没有帮助。

确保您从 Developer Command Prompt 启动 VS Code。这将设置必要的环境变量，包括“cl.exe”的位置。
