这是一个非常奇怪的错误，我无法弄清楚。我花了很长时间才将其缩小到这个 MWE。tex4ht 给出了这个奇怪的错误
(/usr/local/texlive/2016/texmf-dist/tex/latex/graphics-cfg/graphics.cfg)))
Runaway argument?
\:tempc \choose:begin {\let \choose:begin \@firstoftwo \ifx \EndPicture \ETC.
! Paragraph ended before \:tempc was complete.

使用此 MWE
\documentclass[11pt]{article}%
\usepackage{amsmath,mathtools}
\usepackage{hyperref}
\begin{document}
\begin{align}
a &= b
\end{align}
\begin{equation}
a=b
\end{equation}
\end{document}
使用以下方式编译时显示错误
make4ht HW1_solution.tex 'htm,0,pic-align'
Output dir:

执行下列任一操作后，此错误将消失（一次一个）
1）使用make4ht HW1_solution.tex 'htm,0' ie 编译时移除选项pic-align！
2）删除\usepackage{hyperref}！
3）删除\begin{equation块，例如这样
\documentclass[11pt]{article}%
\usepackage{amsmath,mathtools}
\usepackage{hyperref}
\begin{document}
\begin{align}
a &= b
\end{align}
\end{document}
4）删除\begin{align}，像这样
\documentclass[11pt]{article}%
\usepackage{amsmath,mathtools}
\usepackage{hyperref}
\begin{document}
\begin{equation}
a=b
\end{equation}
\end{document}
有人知道这个错误的根源是什么吗？使用 tex live 2016，我刚刚更新了所有内容，所以我拥有最新和最好的版本。有什么解决办法吗？
更新：
错误似乎来自tex4ht-4h.tex里面全是\tempc:东西。我看不懂代码，对我来说太复杂了。我认为世界上只有 5 个人能读懂这段代码。
答案1
这是由于最近\autoref对包提供的修复造成的hyperref。此修复和选项提供的配置中使用了同名的宏pic-align。简单的修复方法是重命名有问题的宏。

有一个问题，方程式图片也包含方程式编号，我们应该在将来修复它，因为它看起来不太好看。
