Question

当我尝试执行 C++ 代码时出现以下错误

In file included from /usr/local/Cellar/gcc/10.2.0_3/include/c++/10.2.0/bits/postypes.h:40,
                 from /usr/local/Cellar/gcc/10.2.0_3/include/c++/10.2.0/iosfwd:40,

                 from main.cpp:1:

      |          ^~~~~~~~~

我在 MacOS Big Sur 11.2 上使用 gcc10 编译器工作正常，直到我更新自制软件或更新到 Big Sur 11.2。运行 brew cleanup 也可能破坏它。我曾尝试取消链接并再次链接 gcc，但这没有任何效果。我能做些什么来修复这个错误？删除并重新安装gcc会更好吗？

通过更新我的 xcode 命令行工具解决了这个问题

致命错误：wchar.h：没有那个文件或目录
