查了好多资料，大多是不能 work 的。感谢这个视频教程：https://www.youtube.com/watch?v=LmR8sRcqbq0，最终帮我完成了需求。

以下是步骤概述：

1、在命令行执行：echo | g++ -v -x c++ -E -，我的运行结果如下：

> echo | g++ -v -x c++ -E -
Apple clang version 16.0.0 (clang-1600.0.26.3)
Target: arm64-apple-darwin23.6.0
Thread model: posix
// 此处省略若干行
#include "..." search starts here:
#include <...> search starts here:
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/16/include
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks (framework directory)
End of search list.
# 1 ""
# 1 "" 1
# 1 "" 3
# 439 "" 3
# 1 "" 1
# 1 "" 2
# 1 "" 2

2、在上一步的结果中，寻找 include <...> search starts here 那一行，在那一行后面有提供 5 个路径，找到中间那个路径，按住 cmd 点击，可以用鼠标打开那个路径。如下图：

3、找开之后，在那个路径新建名为 bits 的文件夹。

4、进入 bits文件夹，随便粘贴一个头文件进去，然后改名为 stdc++.h，修改文件内容如下：
