我刚开始学习 LaTex，并决定用它写我的论文。
我已经构建了 main.tex 文件的基本结构并创建了相应的章节 tex 文件，并使用 /input 将它们添加到主文件中。但是，在我开始编写第 3 章后，它在编译的 PDF 中一直显示为第 4 章。然后我开始在其相应的文件中编写第 4 章，现在 PDF 甚至不再编译。我收到以下错误消息：
我不确定哪里出了问题。有什么想法吗？谢谢您的帮助！如果我需要提供更多信息，请告诉我。
*编辑: 感谢您迄今为止的帮助！我修复了第 4 章中的拼写错误，现在可以再次生成 PDF，还修复了 fancyheadr 问题。但是，章节问题仍然存在……现在第 3 章显示为第 4 章，第 4 章显示为第 6 章！我在每个章节文件的开头添加了 \chapter，然后在 {} 之间添加了章节标题。还在每个章节文件的顶部添加了此行：%!TEX root=main.tex
这是所要求的代码（感谢您的进一步帮助！）：

这是两章（第 3 章和第 4 章）的代码：
%!TEX root=main.tex
\chapter{Brazilian context and the 2013 and 2014 protests in Fortaleza}
\section{Why were people taking to the streets?} %this is an item for broader, structural contextualization
\section{Who were the protesters in 2013 and 2014?} %this is an item for contextualization of the movements themselves and changes between both years through their lenses, which take into account the sociopolitical changes
\section{The Brazilian media landscape}%ver também docs com citações para meu MA e outros artigos que tratam do assunto, mas não pegar os textos em si
\section{Internet use and digital inclusion}

\section{Nigéria, Na Rua and the people around them}%ver o que posso aproveitar do exposé na descrição geral, principalmente dos dois coletivos
\section{Interim summary}
第四章：
%!TEX root=main.tex
\chapter{Literature review on media practices}
\section{Practice theory}
*origins of the concept, canon literature
\section{Practice Theory in the Context of Media Studies}
\section{Media practices in protest movements}
\section{Adaption of media practices}
\subsection{Policitization of everyday media practices}
\subsection{Activismization of professional journalistic practices}
\subsection{Modification/creation of media practices as a reaction to changes in conjuncture}
\section{Interim summary}
现在目录的样子如下：
答案1
根据错误信息，我假设代码中有这样的内容：
\section{Activismization of professional journalistic practices
\subsection{...}
那么原因就是章节标题缺少右花括号。
还应修复\headheight以下警告：fancyhdr
如果
geometry使用包，则添加选项：\usepackage[ ..., headheight=14.5pt, ]{geometry}手动（也许可以修复其他垂直布局长度）：
\setlength{\headheight}{14.5pt}
如果不解决这个问题，布局就会不一致，前几页的页眉会较小\headheight，后面几页的页眉会较大，这会导致正文稍微向下移动。
章节编号问题需要进一步分析：将文件章节信息.log与输出和 TeX 源进行比较。如果问题无法解决，您应该能够缩小问题范围并发布一些相关代码。
