【问题描述】：

我需要能够运行命令latexindent，但我每次都会收到此错误：

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 用 Homebrew 安装了 MacTeX。当我输入命令which latexindent 时，它会给出/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？

【参考方案1】：

基于this question，我找到了解决我的问题的方法：

我删除了：~/perl5、~/.cpan、~/.cpanm； 我重新启动了计算机； 然后我使用命令cpan install Log::Log4perl 安装了Log::Log4perl。那里问我是否要选择自动或 手动配置模式。我选择了自动模式； 然后我根据this post安装了其他模块： SQL::Statement,Text::CSV_XS,DBD::CSV,Log::Dispatch::File,cpan install YAML::Tiny,File::HomeDir,Unicode::GCString,Mac::SystemDirectory;

最后，latexindent --version 命令给了我3.9.1, 2021-03-21 的版本，它可以工作。

不再需要 Log4perl :)
