tex4ht：hyperref 和 cleveref 之间的冲突

Question

梅威瑟：

\documentclass{amsart}
\usepackage{hyperref}
\usepackage{cleveref}

\newtheorem{theorem}{Theorem}

\begin{document}

\begin{theorem}
  \label{test}
  This is a theorem.
\end{theorem}

Look at \Cref{test}.

\end{document}

使用编译时make4ht出现错误

[ERROR]   htlatex: ./test.tex   14   Argument of \@fourthoffive has an extra }.
[ERROR]   htlatex: ./test.tex   14   Paragraph ended before \@fourthoffive was complete.
[ERROR]   htlatex: ./test.tex   14   Argument of \@fifthoffive has an extra }.
[ERROR]   htlatex: ./test.tex   14   Paragraph ended before \@fifthoffive was complete.
[ERROR]   htlatex: ./test.tex   14   Paragraph ended before \hyper@readexternallink was complete.
[ERROR]   htlatex: ./test.tex   14   LaTeX Error: There's no line here to end.

一种解决方法是删除\usepackage{hyperref}它，这似乎不会影响html输出。但是，我想知道为什么它们在 tex4ht 下会发生冲突，以及更好的解决方案。

这是由另一个问题的修复引起的 -Hyperref 和 Biblatex 之间的冲突。如果您不使用 Biblatex，您可以使用此版本的重新引入原始代码cleveref-hooks.4ht：

结果如下：

目前，我不知道适用于所有软件包的正确解决方案是什么。所以这只是一个临时解决方案。
