latexindent：安装File::HomeDir、Mac::SystemDirectory自macOS11BigSur后出现问题

在开始之前，我应该注意，我在 macOS 10.15 Catalina 上从未遇到过这个问题，不幸的是，这个类似线程中的回复并没有解决问题。

我正在尝试latexindent全新安装的 macOS 11 Big Sur，但遇到了以下问题File:HomeDir：运行会latexindent返回完整的错误列表，以Can't locate File/HomeDir.pm in @INC. 我尝试使用cpan安装该模块，但最终得到以下结果：

我真的对 perl 了解不多，但在我看来Mac::SystemDirectory缺少了，但是当我尝试安装它时，我得到了

由此看来，头文件似乎EXTERN.h丢失了，但我不确定从哪里开始。有没有人有任何想法或建议？我为大量代码道歉 - 我认为最好包括所有可能的细节。非常感谢！

注意：我在 LaTeX Stack Exchange 中发布了同样的问题，但我想我也会在这里问，因为它似乎是一个更广泛的 perl 问题。
