我使用 Overleaf 写了一篇论文，并尝试将其上传到 arXiv。当我在 Overleaf 上或在本地使用时，pdflatex main.tex标题中的部分名称是小写的。我得到以下信息：
但是当我上传到 arXiv 时，它却是大写的（这是在处理阶段，它说它成功了）。在这两种情况下，我在标题的右侧都有一个作者姓名，大小写表现符合我的预期（它们之间没有区别）。
这是我的 MWE 的代码：
\documentclass{article}
\usepackage[english]{babel}
\pdfoutput=1
\usepackage{fancyhdr}
\begin{document}
\pagestyle{fancy}
\fancyhf{}
\rhead{Author Name}
\lhead{\nouppercase\leftmark}
\section{Section name}
This is some text
\end{document}
在 Overleaf 上，我使用 TexLive 2023 和 pdflatex 编译器。当我从终端编译它时，我使用 TexLive 2022 和 pdflatex 编译器。我已检查 arXiv 是否使用 TexLive 2023，并且在日志中它确认它正在使用 pdflatex 编译器。
我的问题是为什么 arXiv 会产生不同的结果？我该如何解决这个问题？

这是由 arXiv 的 tex 树中的配置问题引起的，它加载的是版本 3.2，而不是树中的当前版本（实际上是 4.1）。您可以通过下载该版本并尝试在本地编译来在本地复制此行为。
我已经为此提交了一个错误报告，但是现在您只需fancyhdr.sty从本地 tex 安装中添加包即可获得所需的功能。
