我尝试通过自制软件获取gcc。有一些奇怪的问题，所以我删除了自制程序并重新安装它。重新安装成功，我遵循以下规则：What is the best/safest way to reinstall Homebrew?
现在，我像往常一样简单地输入.tablesorter-filter-row{
display : none;
}
然后得到：
brew install gcc所以，我也遵循错误消息提示brew install gcc

的意思，然后得到
brew install gcc@6这是递归的。我对这个问题的猜测可能是我使用的OSX版本太旧了？ （10.10优胜美地）。
我应该获得最新版本的OSX以获得正确的冲泡功能吗？如果您有任何想法，请告诉我。
谢谢

如消息所示，Homebrew不支持您的macOS版本，并且您的Xcode已过时。
如果一切正常，则可以使用不受支持的macOS。但是，过时的Xcode会阻止所有内容。
如果可以，请更新您的Xcode，然后重试。如果仍然无法使用，则必须更新macOS。
