想要为我的代码执行 XgBoost。 Mac：macOS Mojave 10.14.6。 Python 版本：3.8.3。安装 Homebrew。然后在终端中执行命令 brew install libomp。 出现问题：

==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "libomp".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

如何在 Mac 上执行？有什么解决办法吗？
