无法打开源文件“ iostream” C / C ++1696

如何解决无法打开源文件“ iostream” C / C ++1696

有人问过类似的问题，我连续几个小时都在研究这些问题，但没有一个解决方案起作用。当我将Mac更新到Catalina 10.15.7时，我在iostream的include语句中遇到了以上错误。

这是我的属性文件

c_cpp_properties.json：

{
    "configurations": [
        {
            "name": "Mac","includePath": [
                "${workspaceFolder}/**"
            ],"defines": [],"macFrameworkPath": [
                "/System/Library/Frameworks","/Library/Frameworks"
            ],"compilerPath": "/usr/bin/cpp","cStandard": "c11","cppStandard": "c++20","intelliSenseMode": "clang-x64"
        }
    ],"version": 4
}
