test中main.cpp报错无法产生头文件但是可以正常编译运行

如图，提示头文件缺失，并报错std为未声明标识符，但字build文件夹下已产生compile_command.json。输入图片说明

正常编译是指的那些可以正常编译？

通过 Code Runner 插件运行？
调试？

如果确认 compile_commands.json 等都没有问题，那问题应该是

没有重启 VSCode 或者重启 clangd 拓展，重启即可。
以前在电脑上安装了旧版本 llvm，请在终端输入 clangd --version 确认一下版本是否是 17.0.4，如果不是，参考此处进行修复。

正常编译运行：
通过code runner 运行结果输入图片说明，运行结果与warning提醒数正常，
调试：调试四种方法正常，可以正常执行至断点，并且最后输出无误。
关于llvm版本：版本无误且路径选择无误。
clangd扩展与vscode重启：已进行过vscode Reload window，且clangd插件未提示需要进行重启以运行输入图片说明。
compile_commands.json内容：
在尝试以上解决方法后还是出现了不应该出现的报错信息，请问如何进行修正。

问题是否与clang target相关？注意到target为gnu，与其余issue中不一致

和这个没关系

能看看 clangd 的输出吗？全选以文本形式粘贴过来。

```
粘贴过来
```

输入图片说明

compile_commands.json 也粘贴成文本看看吧，截图不全。

clangd在运行和调试后的输出：I[15:13:49.595] clangd version 17.0.3 (https://github.com/llvm/llvm-project 888437e1b60011b8a375dd30928ec925b448da57)

可能是我更新教程时不小心把自己电脑上的配置更新过去了，你可以尝试【左下角齿轮】-【设置】-【右上角打开设置】，将 398 行的 "--query-driver=/opt/homebrew/bin/*", 删去。

或者下载更新后的配置文件，重新导入并覆盖配置文件。

将这一行注释掉后报错依然没有得到解决，此时clangd输出内容如下：

这我就实在不清楚了，可能是你电脑里安装的 Microsoft Visual Studio 9.0 Microsoft Visual Studio 8 等 Visual Studio 软件的问题。这属于巧合引发的问题，只能反复尝试了，从上往下依次试试吧（每一步做完都记得重启 clangd）：

试试在设置里加上一行 "clangd.path": "clangd",。
按教程里说的，再进入环境变量，将教程中加的 msys2 路径移到更前面。
删除 .cache 文件夹和 build 文件夹，用 CMake 重新选择 clang 17.0.4 进行配置，重启 clangd。
卸载这些冗余的 Visual Studio 软件。

我也碰到了类似的问题，我似乎用如下方法正确解决了
输入图片说明
就是将我系统内所有编译器的路径以逗号分隔的形式加入到querydriver中

教程里针对 gcc 说过这个，但忘了其实可以用在这地方了，感谢。
