该软件包的lipsum行为很奇怪，我不知道为什么。它以前工作正常。问题突然出现，并且发生在我用来编码的所有三台电脑上。我尝试了不同的编译器、文档类和磁盘上源文件的不同位置。我还lipsum使用 MiKTeX Console 的软件包管理器重新安装了该软件包。这是我的代码：
\documentclass{report}
\usepackage{lipsum}
\begin{document}
\lipsum
\end{document}
我很难想象这样会有什么问题，但下面是我得到的输出片段（请注意前五个字符，以及以下文本甚至不是以“Lorem ipsum...”开头）：
等等。编译产生三个错误；这里是从 .log 文件中摘录的：

{document}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
! Use of \??? doesn't match its definition.
<argument> \???
! LaTeX cmd Error: Invalid argument {\__int_eval_end: } to ...
l.5 \end
{document}
If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are
made up of letters only. The macro here has not been
followed by the required stuff, so I'm ignoring it.
! Missing number, treated as zero.
<to be read again>
\tex_let:D

{document}
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

这怎么可能呢？提前感谢大家提出的任何建议。
