我有一个 references.bib 文件，但是当我加载论文时，我的参考书目列表中只有一个参考文献，而我尝试使用 \cite 引用的其他几个参考文献都出现了“？”，尽管名称引用正确。
我知道这个问题与我加载的包及其顺序有关。我认为部分错误来自那里。目前，我更关心的是拥有完整的列表，而不是样式。
\documentclass{article}
\usepackage[utf8]{inputenc}
% Required package
\usepackage{amsmath}
\usepackage{multirow}
\usepackage{float}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{threeparttable}
\usepackage{apacite}
\usepackage{multirow}
\usepackage{ulem}
\usepackage[table]{xcolor}
\usepackage{longtable}
\usepackage{pdflscape}
\usepackage{fancyhdr}
\usepackage{afterpage}
\usepackage{geometry}
\begin{document}
\subsection{A}
\cite{Dustmann_1996}.
\cite{Kuhlenkasper_2012}.
\section{A}
\begin{document}
\bibliography{references.bib}
\bibliographystyle{apacite}
\end{document}
\appendix
\section{Appendix}
\setcounter{table}{0}
\renewcommand{\thetable}{A\arabic{table}}
\begin{table}[H]
\caption{Tabulation of x information}
\label{Tabulation of x information}
\end{tabular}
\end{table}
\end{document}
最后的 \bibliography 部分出现错误，例如：输入行 27 上的引文“Kuhlenkasper_2012”未定义。 \bibliography{references.bib} 失控参数？l.33 \begin{document} 只能在序言中使用
这是我的references.bib（也包含其他参考资料）

答案1
代码中有两个主要问题（除了制作 MWE 的一些问题，例如两个\begin{document}语句等）。
第一个是使用ulem包进行下划线。默认情况下，此包重新定义\emph（用于强调参数的命令，默认情况下为斜体）以生成下划线。Apacite 在参考书目中使用，这会导致错误。可以使用 的包选项（即删除和添加 ）\emph来修复此问题。normalemulem\usepackage{ulem}\usepackage[normalem]{ulem}
第二个问题是 Apacite 无法识别url（@techreport但可以识别@article）。因此，url 格式不适用于条目中的网址Kuhlenkasper_2012。由于该 url 包含_另一个错误，因此出现。要解决此问题，您可以使用howpublished = {\url{...}}。这需要\usepackage{url}。
E另一个小改进是在周围增加了一组括号The {E}uropean Experience以防止自动小写。
