我在使用Home-brew安装OpenMPI时遇到问题，四处搜寻后，我找不到任何答案。我这样做是因为从GitHub安装R软件包时，我收到此错误：
clang: error: unsupported option '-fopenmp'
建议似乎是在这种情况下，应该使用自制软件重新安装openmpi。当我这样做时，会收到以下响应：
brew reinstall openmpi --build-from-source

我似乎还不太了解，我已经运行过brew医生，它告诉我有一堆.config文件等可能使它困惑，但我并不热衷删除/移动那些文件，因为我不知道它们是否是其他事物的依赖项。有人可以让我直接在这里吗？
非常感谢您的答复
