\documentclass{sn-jnl} 的问题

如果我尝试使用 pdflatex（或仅 latex）编译以下简单代码（sn-jnl.cls 是 Springer 期刊的文档类，因此我认为它被广泛使用......）

\documentclass{sn-jnl}

\usepackage{xcolor}

\begin{document}
    
\title{My Title}

\maketitle

\section{Introduction} 

My Intro

\end{document}

我收到错误消息

Undefined control sequence. \begin{document}

并且，如果我查看日志文件，我会读到（在某个时候）：

! Undefined control sequence.

实际上，在 sn-jnl.cls 中你可以看到以下几行

\AtBeginDocument{%
%%\newcommand*\ExtraParaSkip{12pt}%
\SetFootnoteHook{\hspace*{-8pt}}%
\DeclareNewFootnote{A}[gobble]%
\setlength{\skip\footinsA}{0pt}}%

我不明白这里的问题。

我从 Springer 网站下载了 sn-jnl.cls。

我在 MacOS 上使用 MikTeX。

谢谢 Maurizio

答案1

问题与如何修复过大的徽标？。

类开发人员决定避免加载该类的上一版本所加载的所有包，但这样做他们也删除了该类本身所依赖的包。他们甚至没有更改版本号！

解决方案：

\documentclass{sn-jnl}

\usepackage{amsmath}
\usepackage{manyfoot}
\usepackage{xcolor}

\begin{document}

\title{My Title}

\maketitle

\section{Introduction}

My Intro

\end{document}

答案2

我找到了一个解决方案。您必须添加 sn-jnl 自身无法加载的软件包：

\usepackage{manyfoot}
\usepackage{xcolor}
\usepackage{amsmath}

坦白说，我认为 Springer 的这篇文章太糟糕了……

您是否知道这个问题是否已在 documentclass 的某个版本中修复（但我是从 Springer 网站下载的...）？？？

谢谢
