我有一个由许多子文档组成的文档。这些文档可以使用 LaTeX 和软件包分别编译，subfiles但当我同时使用newtxtext和时bm则不行。我该如何解决这个问题？
例如，文件main.tex：
\documentclass{report}
\usepackage{newtxtext}
\usepackage{newtxmath}
\usepackage{bm}
\usepackage{subfiles}
\begin{document}
\subfile{sub1}
\end{document}
sub1.tex同一目录中的文件：
\documentclass[main]{subfiles}
\begin{document}
$\bm{x}$
\end{document}
主文件编译没有问题，但尝试单独编译 sub1 会报告错误，但仅当newtxtext包含时才会报告错误。
日志文件告诉我
Runaway argument?
{document}\ifx \reserved@a \@currenvir \else \@badend {document}\fi \clearpage
\ETC.
! File ended while scanning use of \reserved@a.
<inserted text>
\par
<*> \input sub1.tex
I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.
! Emergency stop.
<*> \input sub1.tex
*** (job aborted, no legal \end found)
$\bm{x}$在和 之间添加一个段落分隔符，\end{document}可以传达以下信息
! Paragraph ended before \bm@test@token was complete.
搜索此消息提出了一个问题软件包不兼容：etoolbox、hyperref 和 bm，独立吗？。这可能是类似的问题吗？
添加\listfiles可得到

受到这个问题的启发软件包不兼容：etoolbox、hyperref 和 bm，独立吗？，etoolbox.sty我注释掉了
\patchcmd\enddocument
{\deadcycles}
{\let\AfterEndDocument\@firstofone
\@afterenddocumenthook
\deadcycles}
{}
{\let\etb@@end\@@end
\def\@@end{%
\let\AfterEndDocument\@firstofone
\@afterenddocumenthook
\etb@@end}}
{<environment>}{<code>}
这样就可以sub1.tex自行编译而不会出现错误。这表明存在链接问题中描述的类型的冲突。
答案1
该newtxtext包加载了etoolbox重新定义 的包\@@end。它真的不应该这样做。既然如此，您可以这样做以在本地恢复它。
\makeatletter
\let\@@@@@@end\@@end
\def\fixend{\let\@@end\@@@@@@end}
\makeatother
\documentclass[main]{subfiles}
\begin{document}
$\fixend\bm{x}$
\end{document}
