我想使用 texlive 2018 版本对 beamer 书签中的每个部分、子部分和子子部分进行编号。根据提供的解决方案，这个问题似乎很多年前就解决了网络奇点有问题在 Beamer 中调整书签编号。
我关注了它，在 texlive 2017 中解决了这个问题然而，去年我无法编译代码2018 年 TEXLIVE在 Windows 操作系统上：
书签是：
代码如下：
\documentclass{beamer}
\documentclass{beamer}
\hypersetup{
bookmarksnumbered=true
}
\setcounter{tocdepth}{4}
% get numbering in section bookmarks
\usepackage{etoolbox}
\usepackage{bookmark}
\makeatletter
\newcounter{realsection}
\newif\ifrealsection
\long\def\beamer@@ssection*#1{\realsectionfalse\beamer@section[{#1}]{}}
\long\def\beamer@@@section#1{\realsectiontrue\beamer@section[{#1}]{#1}}
\patchcmd{\beamer@section}%
{\refstepcounter{section}}%
{\ifrealsection\refstepcounter{realsection}\fi\refstepcounter{section}}%
{}{\errmessage{failed to patch}}
\patchcmd{\beamer@section}%
{\Hy@writebookmark{\the\c@section}{\secname}}%
{\Hy@writebookmark{\the\c@section}{\numberline{\therealsection}\secname}}%
{}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsection}%
{\Hy@writebookmark{\the\c@subsection}{#2}}%
{\Hy@writebookmark{\the\c@subsection}{\numberline{\therealsection.\thesubsection}#2}}%
{}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsubsection}%
{\Hy@writebookmark{\the\c@subsubsection}{#2}}%
{\Hy@writebookmark{\the\c@subsubsection}{\numberline{\therealsection.\thesubsection.\thesubsubsection}#2}}%
{}{\errmessage{failed to patch}}
\makeatother
\begin{document}
\section*{Intro}
\section{section}
\begin{frame}
\end{frame}
\subsection{subsection}
\begin{frame}
\end{frame}
\subsubsection{subsubsection}
\begin{frame}
\end{frame}
\section{section}
\begin{frame}
\end{frame}
\subsection{subsection}
\begin{frame}
\end{frame}
\subsubsection{subsubsection}
\begin{frame}
\end{frame}
\subsubsection{subsubsection}
\begin{frame}
\end{frame}
\end{document}
所以，我如何修改上面的代码并编号子节和子节？
非常感谢您的帮助。

beamer 现在还使用 subsection 和 subsubsection 命令 \subsecname 和 \subsubsecname：
\documentclass{beamer}
\hypersetup{
bookmarksnumbered=true
}
\setcounter{tocdepth}{4}
% get numbering in section bookmarks
\usepackage{etoolbox}
\usepackage{bookmark}
\makeatletter
\newcounter{realsection}
\newif\ifrealsection
\long\def\beamer@@ssection*#1{\realsectionfalse\beamer@section[{#1}]{}}
\long\def\beamer@@@section#1{\realsectiontrue\beamer@section[{#1}]{#1}}
\patchcmd{\beamer@section}%
{\refstepcounter{section}}%
{\ifrealsection\refstepcounter{realsection}\fi\refstepcounter{section}}%
{}{\errmessage{failed to patch}}
\patchcmd{\beamer@section}%
{\Hy@writebookmark{\the\c@section}{\secname}}%
{\Hy@writebookmark{\the\c@section}{\numberline{\therealsection}\secname}}%
{}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsection}%
{\Hy@writebookmark{\the\c@subsection}{\subsecname}}%
{\Hy@writebookmark{\the\c@subsection}{\numberline{\therealsection.\thesubsection}\subsecname}}%
{}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsubsection}%
{\Hy@writebookmark{\the\c@subsubsection}{\subsubsecname}}%
{\Hy@writebookmark{\the\c@subsubsection}{\numberline{\therealsection.\thesubsection.\thesubsubsection}\subsubsecname}}%
{}{\errmessage{failed to patch}}
