我刚刚从以下网址下载了 Legrand Orange Book 模板：
http://www.latextemplates.com/template/the-legrand-orange-book
我还没有修改它。但是，当我尝试编译它时，我收到以下错误：
! Undefined control sequence.
<argument> ...docsvlist \expandafter {\bbl@loaded
}\ifboolexpr { not test {\...
l.51 \begin{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.
我搜索了类似的问题，但只发现有关编译同一模板的修改版本时出错的帖子，而未修改的版本运行良好（所以我希望这不会被视为重复）
在 Legrand Orange Book 模板上使用修改后的 structure.tex 时出错
据我所知，未定义的 \begin{document} 错误通常与包有关。我没有包含 MWE，因为我没有修改模板，它立即给我这个错误。但我会列出它使用的包（存在于 structure.tex 中）：

答案1
作为克里斯蒂安·胡普弗建议，这是我的 MiKTeX 发行版过时的问题，如 所示\listfiles。我的发行版无法同步，我必须重新安装它才能工作。重新安装后，模板完美运行。
