我需要能够运行命令latexindent，但我每次都会收到这个错误：
Unknown PerlIO layer 'encoding' at /usr/local/texlive/2021/texmf-dist/scripts/latexindent/LatexIndent/Document.pm line 21.

我通过这个命令brew install--cask mactex安装了带有Homebrew的MacTeX。当我键入命令哪个latexindent时，它会给出这个/usr/local/texlive/2021/bin/verity-darwin/latexindent。我有Perl v5.34.0，它在这里/select/hombrew/bin/perl。
如何设置PerlIO的编码？
我通过自制软件安装latexindent解决了这个问题。命令是brew install latexindent。我在MacOS Monterey 12.4上
基于这个问题，我找到了这样一个解决我问题的方法：
~/perl5，~/. cpan，~/.cpanm；安装了日志::Log4perlcpaninstall日志::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；SQL::语句，文本::CSV_XS，DBD::CSV，日志::Dispatch::File，cpan安装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并且它有效。
