latexindent：未知的 PerlIO 层“编码”-格式化失败，退出代码为 255 macOS 12 Monterey

【中文标题】latexindent：未知的 PerlIO 层“编码”-格式化失败，退出代码为 255 macOS 12 Monterey

【英文标题】：latexindent: Unknown PerlIO layer 'encoding' - Formatting failed with exit code 255 macOS 12 Monterey

【发布时间】：2022-01-16 00:48:18

【问题描述】：

我尝试使用 LaTeX Workshop 在 Visual Studio Code (1.63.0) 在 macOS (12.0.1) 下运行 latexindent > 插件 (v8.22.0)。 它不起作用，因为在格式化过程中发生错误。

我已经安装了这些 cpan 包：

Lo​​g::Log4perl (1.54) Lo​​g::Dispatch::File (2.70) YAML::Tiny(1.73) 文件::HomeDir (1.006) Unicode::GCString (2013.10) 文件::HomeDir (1.006) Mac::SystemDirectory (0.13)

我还尝试使用此命令更新 CPATH 环境变量

export CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX12.0.sdk/System/Library/Perl/5.34/darwin-thread-multi-2level/CORE:$CPATH

这也不起作用。

Perl 可执行文件位于此文件夹中：/opt/homebrew/bin/perl。我有版本 v5.34.0。 我已经读过这个latexindent: trouble installing File::HomeDir, Mac::SystemDirectory since macOS 11 Big Sur。

谁能给我一些关于如何解决这个问题的提示？

这是错误输出：

【问题讨论】：

您似乎缺少 Perl 本身的一部分？！

latexindent 脚本中的 shebang 行是什么？试试输入head -1 /Library/TeX/texbin/latexindent

这是 latexindent 脚本中的 shebang 行：#!/usr/bin/env perl@HåkonHægland

@DanielSchreurs 好的，我要看看这个。你是如何安装latexindent的？那我先从tring开始重现你遇到的错误

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。 @HåkonHægland 我尝试综合并主要隔离我的问题here 与一个新帖子。

【参考方案1】：

这个问题与macOS下latexindent的安装有关。我已经向here 提出了与此问题相关的更具体的问题，并给出了我的解决方案。
