我需要能够运行命令latexindent，但每次都会出现以下错误：
Unknown PerlIO layer 'encoding' at /usr/local/texlive/2021/texmf-dist/scripts/latexindent/LatexIndent/Document.pm line 21.
Unknown PerlIO layer "encoding" at /opt/homebrew/Cellar/perl/5.34.0/lib/perl5/5.34.0/open.pm line 126.

我通过这个命令brew install --cask mactex安装了带有Homebrew的MacTeX。当我键入命令which latexindent时，它会给出这个/usr/local/texlive/2021/bin/universal-darwin/latexindent。我有Perl v5.34.0，它在这里/opt/homebrew/bin/perl。
如何设置PerlIO的编码？
我通过自制程序安装latexindent解决了这个问题。命令为brew install latexindent。我在MacOS Monterey 12.4 上
基于这个问题，我找到了这样一个问题的解决方案：
- 我删除了：
~/perl5、~/.cpan、~/.cpanm - 我重新启动了电脑
- 然后我用命令
cpan install Log::Log4perl安装了Log::Log4perl。在那里，它问我是想选择自动还是手动配置模式。我选择了自动模式 - 然后我在此基础上安装了其他模块帖子：
SQL::Statement、Text::CSV_XS、DBD::CSV、Log::Dispatch::File、cpan install YAML::Tiny、File::HomeDir、Unicode::GCString、Mac::SystemDirectory
最后命令latexindent --version给了我版本3.9.1, 2021-03-21，它就工作了。
