【问题描述】：
当我尝试使用 rbenv 在我的 Mac 上安装 ruby2.6.6 时，我收到了“Builed Failed”消息。
一开始我是这样运行的
% rbenv install 2.6.6

正如您在输出中看到的，“正在检查 C 编译器是否工作......不”，我认为编译器工作不正常并寻找解决方案。
有一个解决方案可以通过指定 GCC 路径来运行它，我用它作为参考来运行它，如下所示。
CC=/usr/bin/gcc rbenv install 2.6.6
但是，结果是“构建失败”。
gcc的版本如下
%gcc --version
Configured with: --prefix=/Applications/Xcode-beta.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 13.0.0 (clang-1300.0.29.3)
Target: x86_64-apple-darwin21.1.0
Thread model: posix
InstalledDir: /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
指定gcc路径时的输出和日志如下。
% CC=/usr/bin/gcc rbenv install 2.6.6

我认为 gcc 没有正确编译，所以我尝试使用自制软件重新安装它，但没有成功。
我无法找到解决此问题的方法。如果有人能告诉我该怎么做，我将不胜感激。
