我在 overleaf 上有一个项目，它由多个目录组成，所有目录都具有共同的序言和共同的外观。
每个文件夹包含 main.tex，并创建一个 pdf。源代码使用 beamer 类。此代码在 overleaf 中有效，但下载到我的计算机并使用 latexmk 进行构建时，出现故障：
\documentclass[xcolor=table]{beamer}
\input{Preamble/commands.tex}
\title[]{test}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{withoutheadline}
\begin{frame}{Slide 1}
Testing testing 123
$O(n)$
\end{frame}
\end{withoutheadline}
\begin{frame}{Slide 2}
Test 2
\end{frame}
\end{document}
我将附加整个命令文件以确保完整性，但失败的行是：
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}
完整文件为：

答案1
该文件包含多个错误，就像在本地 tex 安装中一样，在 overleaf 上进行报告。
看
https://www.overleaf.com/read/yqwnftmqfynt#522d04
其中有
因此日志中报告了 8 个错误，错误行上也用红色斑点表示：
如果我注释掉
%\includegraphics[width=2cm]{Preamble/logo.pdf}%
然后它在 Overleaf 和本地都可以无错误地运行。
\newcolumntype来自数组包，它通过colortblas beamerloads加载xcolor，使用table选项
\documentclass[xcolor=table]{beamer}
无关但不要使用
\usepackage[latin1]{inputenc}
在 UTF-8 编码的文件上。（本网站和 Overleaf 始终使用此编码）
