在 beamer 中出现错误“环境索引未定义”

对于以下 tex，我收到“Enviroment theindex undefined”错误。我没有在 .tex 的任何部分使用索引。但是当我使用“\newenvironment{theindex}”或“\renewenvironment{theindex}”时，它仍然说 theindex 已经定义。你有什么建议？

\documentclass{beamer}
\setbeamertemplate{navigation symbols}{}
\usepackage{graphicx}
\usepackage{amsmath,amssymb,enumerate,algorithm,ifthen,algorithmic,epsfig}
\usepackage{epstopdf}
\usetheme{Berkeley}
\beamersetuncovermixins{\opaqueness<1>{25}}{\opaqueness<2->{15}}
\setbeamertemplate{sidebar right}{}
\setbeamertemplate{footline}{%
\hfill\usebeamertemplate***{navigation symbols}
\hspace{1cm}\insertframenumber{}/\inserttotalframenumber}
\usepackage[nottoc]{tocbibind}

\begin{document}

\begin{frame}

\end{frame}

\end{document}

tocbibind 您的代码无法编译，因为您正在加载与目录/索引有关的包，而这自然不是为幻灯片集定义的。因此，在您不需要有问题的包后，一切都会好起来。

顺便说一句，你的还不够最小工作示例。
