更新到最新版本的 MacTeX 和 TeXmaker 后，我只能在caption一份 LaTeX 文档中使用软件包中的粗体字体。其他所有文档都允许这样做，没有任何问题。
具体来说，在我所有文件的序言中，我
\usepackage[labelfont=bf]{caption}
但在编译有问题的文档时，收到错误消息
Unknown option `labelfont=bf` for package `caption`
该错误将我引导至caption.sty
\newsavebox{\as@captionbox}
我已按照 CTAN 文档尝试过
\usepackage[labelfont=bf]{caption}[2020/09/12]
\usepackage{caption}
\captionsetup{labelfont=bf}
并且还包括\captionsetup{...}图形环境本身。
我的第 78 行.tex没有引用数字，只包含数学模式中的文本\tt，并且\textit
当我尝试通过 MRE 重现该错误时，该错误消失了。
例如
\documentclass[12pt]{article}
\usepackage[labelfont=bf]{caption}
\UseRawInputEncoding
\begin{document}
\begin{figure}[H]
\caption{Lorem ipsum dolor}
\end{figure}
\end{document}
这个问题类似，但目的不同
编辑
审查我的日志文件后，我发现了以下情况\newsavebox{\as@captionbox}
Package: caption v1.4b <1995/04/05> (Harald Sommerfeldt)
\captionmargin=\skip56
! LaTeX Error: Unknown option `labelfont=bf' for package `caption'.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.78 \newsavebox
{\as@captionbox}
The option `labelfont=bf' was not declared in package `caption', perhaps you
misspelled its name. Try typing <return> to proceed.
