LaTeX论文主文档恢复\maketitle后编译报错，请求技术协助

问题描述 #

原本运行正常的毕业论文LaTeX主文档，误删\maketitle命令后重新添加，现在无法编译执行并报错，需排查解决。

原始代码 #

% Thesis master document
 \documentclass[final,12pt,a4paper,oneside]{book}
 \setcounter{secnumdepth}{3}
  \textheight =24.2 cm 
 \textwidth =15 cm 
 \topmargin =-15mm

 \end{document}

错误排查与修复方案 #

1. 语法错误：缺失命令前缀反斜杠

   • 多个usepackage命令缺少\，比如usepackage{graphicx}应改为\usepackage{graphicx}，这是编译失败的核心原因之一
   • 自定义命令def\hang和def\rf缺少\，需改为\def\hang{\hangindent\parindent}和\def\rf{\par\noindent\hang}

2. 逻辑冲突：\maketitle位置与自定义标题页重复

   • 在book文档类中，\maketitle会自动生成标题页，但你已经通过\include{Title}引入了自定义标题页，两者重复会导致排版冲突。建议移除\maketitle，保留自定义的Title.tex标题页即可。
