这个 MWE 花了我两天 8 个小时才找到可能出现问题的地方.........太累了.....

问题 1- 可能与totpages包冲突。我们似乎无法使用

    after title               = {Page~\thepage\ of~\pageref{TotPages}},

它无法编译并给出一个fatal error。

问题 2- 可能与enumerate包冲突。enumerate环境无法使用。如果是这样，则会出现同样的错误

! pdfTeX error (ext4): link annotations cannot be inside an XForm.
<argument> ...shipout:D \box_use:N \l_shipout_box 
                                                  \__shipout_drop_firstpage_...
l.75 }

有什么建议么？

答案1

您的问题与 有关transparency group。当您使用该 tcolorbox/tikz 时，会将框放在 xform 对象中，并且不允许在此类对象中放置链接。

获取错误的一个简单示例（在第二次编译时）是这样的：

\documentclass{article}
\usepackage{hyperref}
\usepackage{tcolorbox}
\tcbuselibrary{skins}
\tcbset{tikz={transparency group},enhanced}

\begin{document}
\section{abc}\label{sec}

\begin{tcolorbox}
hello \ref{sec}
\end{tcolorbox}

\end{document}

您在此处的选择是删除transparency group或避免 tcolorbox 内的任何活动链接，例如通过使用\pageref*和\ref*，或者 - 可能更安全 - 用环境围绕框NoHyper。
