为什么 latexml 不能识别“appendix”包中的“\appendixpage”？

brew install latexml这是 latexml (安装在 OS X 上)的一个错误：

这是乳胶：

\documentclass[10pt]{book}
\usepackage{appendix}

\begin{document}

\appendix
\appendixpage
\addappheadtotoc

\appendix
\chapter[Chapter]{Chapter}
\chaptermark{Chaptermark}

Here's a chapter.

\end{document}

该软件包的（“未完全实现的”）代码位于https://github.com/brucemiller/LaTeXML/blob/master/lib/LaTeXML/Package/appendix.sty.ltxml，并且不包含\appendixpage命令（它在第 28 行被注释掉了）。这解释了为什么会出现错误。要修复错误，您可以按照 David Carlisle 的建议进行近似处理：\providecommand{\appendixpage}{\part*{\appendixname}}。您也可以尝试从包中复制定义，但有几个定义需要您进行跟踪。
