尽管启用了 `--shell-escape`，Markdown 包仍然不起作用

Question

我正在尝试使用这个markdown 包. 我尝试编译该文档

\documentclass{article}
\usepackage{markdown}
\begin{document}
    \begin{markdown}
        _Hello,_ [Stack Exchange](http://tex.stackexchange.com)!
    \end{markdown}
\end{document}

。pdflatex -shell-escape在生成的 pdf 中，我只得到了打字机字体的 markdown 代码。日志文件中有趣的部分似乎是

\openout3 = `document.markdown.in'.

Package markdown Info: Buffering markdown input into the temporary input file "
document.markdown.in" and scanning for the closing token sequence "\end{markdow
n}" on input line 4.
Package markdown Info: The ending token sequence was found on input line 6.
Package markdown Info: Including markdown document "./document.markdown.in" on 
input line 6.
\g_tmpa_iow=\write6
\openout6 = `document.markdown.lua'.


Package luabridge Info: Writing a helper Lua script to file
(luabridge)             \markdownOptionHelperScriptFileName 


Package luabridge Info: Executing a helper Lua script from file
(luabridge)             \markdownOptionHelperScriptFileName 


(|texlua ./document.markdown.lua)
(./_markdown_document/9d5242e42cdbaaa17c844f6b5db64466.md.tex) [1

{/usr/local/texlive/2022/texmf-var/fonts/map/pdftex/updmap/pdftex.map}] (./docu
ment.aux)

我觉得这没什么问题；至少我没有看到任何错误消息。日志中提到的 tex 文件显示

\markdownRendererDocumentBegin
\markdownRendererInputVerbatim{./_markdown_document/9d5242e42cdbaaa17c844f6b5db64466.verbatim}\markdownRendererDocumentEnd

而该文件又只是原始的 markdown。调用\markdownRendererInputVerbatim似乎错误，只给出了宏的名称。出了什么问题？

对于本网站的代码块，缩进 4 个空格意味着逐字

\documentclass{article}
\usepackage{markdown}
\begin{document}
\begin{markdown}
  _Hello,_ [Stack Exchange](http://tex.stackexchange.com)!
\end{markdown}
\end{document}
