第一章的代码（第1章)如下：
\chapter{Introduction}
\label{chapter1:Introduction}
According to survey research conducted by Wang\cite{chisholm2005compack} around 1.7MB of data is being generated every day around the world. This survey report expresses the importance of text mining and sentiment analysis in our daily life.
\section{My heading}
text under my heading.
bib 文件的代码（我的参考文献)如下：
@article{chisholm2005compack,
title={COMPACK: a program for identifying crystal structure similarity using distances},
author={Chisholm, James Alexander and Motherwell, Sam},
journal={Journal of applied crystallography},
volume={38},
number={1},
pages={228--231},
year={2005},
publisher={International Union of Crystallography}
}
当我运行代码时发现以下错误：
！缺失数字，视为零。} l.5 \section{我的标题}
删除之后\section{My heading}，发现以下错误。
! 缺失数字，视为零。} l.1 \begin{thebibliography}{}
删除后\bibliography{reference/myrefs}，代码运行正常。我该怎么办？有人能告诉我吗？
答案1
其中的 Koma-script 类scrbook与该包不兼容titlesec。以下文档由您的文档的几行组成。
\documentclass{scrbook}
\usepackage[compact]{titlesec}
\begin{document}
\section{My heading}
\end{document}
结果是
! Missing number, treated as zero.
<to be read again>
}
l.4 \section{My heading}
?
我建议删除该\usepackage[compact]{titlesec}行settings.tex。
