如果我删除tex4ht包或bmpsize包，一切都会正常工作。（好吧，如果有正确名称的 .png 文件，它就可以正常工作。但是即使没有，也会收到此错误。）
答案1
看起来两者tex4ht都bmpsize试图重新定义\includegraphics，而这些重新定义相互冲突。有两种选择：
bmpsize为包制作 tex4ht 配置文件并解决冲突- 编辑您的文档以不
bmpsize包括tex4ht
选项 2 更容易做到，选项 1 需要有人了解graphicx、bmpsize和tex4ht包。如果您只包含png受支持的图像tex4ht，我认为您不需要bmpsize包：
\documentclass{article}
\makeatletter
\@ifpackageloaded{tex4ht}{}
{\usepackage{bmpsize}}
\usepackage{graphicx}
\begin{document}
\includegraphics[natwidth=1594.7871bp,natheight=1147.85222bp,width=0.65\textwidth,height=0.65\textwidth]{torus-lores-bw.png}
\end{document}
