无法使用预构建的Clang二进制文件构建cpp：找不到文件wchar.h

我正在使用MacOS 10.15。由于MacOS附带的clang不包含clang-format，所以我从这里安装了另一个预编译的clang二进制文件。我已将该二进制文件的路径添加到了PATH变量中。\n

export PATH="$HOME/tools/clang+llvm-10.0.0-x86_64-apple-darwin/bin:$PATH"

\n我尝试编译一个简单的程序：\n

#include 
int main(int argc, char *argv[]) {
    std::cout << "Hello world!\n";
    return 0;
}

\n使用以下命令：\n

clang++ hello.cpp -o hello

\n我得到了以下错误：\n

In file included from hello.cpp:1:
In file included from /Users/jdhao/tools/clang+llvm-10.0.0-x86_64-apple-darwin/bin/../include/c++/v1/iostream:37:
In file included from /Users/jdhao/tools/clang+llvm-10.0.0-x86_64-apple-darwin/bin/../include/c++/v1/ios:214:

#include_next 
              ^~~~~~~~~
1 error generated.

\n我发现这个预编译包中附带的wchar.h在以下目录中：\n

/Users/jdhao/tools/clang+llvm-10.0.0-x86_64-apple-darwin/include/c++/v1/

\n因此我添加了-I标志：\n

clang++ -I /Users/jdhao/tools/clang+llvm-10.0.0-x86_64-apple-darwin/include/c++/v1 hello.cpp -o hello 

\n错误仍然存在。\n如果我使用MacOS附带的clang++，编译源代码时没有任何问题：\n

# 在没有任何错误的情况下正常工作
/usr/bin/clang++ hello.cpp -o hello

\n我在这里、这里和这里看到了一些帖子，但这些解决方案不适用。
