书目愚蠢错误

Question

我的老师给了我thebibliography代码，我复制了它：

\documentclass[12 pt,handout,notheorems, serif]{beamer}
\usepackage{pgfpages}
\pgfpagesuselayout{resize to}[a4paper,landscape]
\usetheme{Boadilla}

\begin{document}
    \underline{References}:
    
    \begin{thebibliography}{9}
        \setbeamertemplate{bibliography item}[book]        
        \bibitem \textit{Control Systems Engineering}, By Norman S. Nise, $7^{th}$ edition, John Wiley \& Sons, 2015. 
        \bibitem \textit{Modern Control Systems}, By Richard C. Dorf and Robert H. Bishop, $12^{th}$ edition, Pearson Education, Inc., 2011. 
    \end{thebibliography}
\end{document}

但是，我收到了这个错误信息：

Missing \endcsname inserted. ...\textit }{\hyperlink {beamerbib\textit }{1}}

输出：

他使用 TexShop，我使用 TeXstudio。可能存在什么问题？

Answer 1

该宏\bibitem需要一个用作标识符的参数，并且可以在中使用\cite。因此你需要类似

    \begin{thebibliography}{9}
        \setbeamertemplate{bibliography item}[book]     
        \bibitem{A} \textit{Control Systems Engineering}, By Norman S. Nise, $7^{th}$ edition, John Wiley \& Sons, 2015. 
        \bibitem{B} \textit{Modern Control Systems}, By Richard C. Dorf and Robert H. Bishop, $12^{th}$ edition, Pearson Education, Inc., 2011. 
    \end{thebibliography}

对于 MWE 来说，完成之后可能看起来像

\documentclass[12 pt,handout,notheorems, serif]{beamer}
\usepackage{pgfpages}
\pgfpagesuselayout{resize to}[a4paper,landscape]
\usetheme{Boadilla}

\begin{document}
\begin{frame}[t]
\frametitle{References}

    \begin{thebibliography}{9}
        \setbeamertemplate{bibliography item}[book]     
        \bibitem{A} \textit{Control Systems Engineering}, By Norman S. Nise, $7^{th}$ edition, John Wiley \& Sons, 2015. 
        \bibitem{B} \textit{Modern Control Systems}, By Richard C. Dorf and Robert H. Bishop, $12^{th}$ edition, Pearson Education, Inc., 2011. 
    \end{thebibliography}
\end{frame}
\end{document}
