\@gobble 的参数有一个额外的 }

Question

当我从我的研究论文中删除作者隶属关系时，出现错误“ argument of \@gobble has an extra }.”请帮我修复它。

\documentclass{svjour3} 
\begin{document} 
\title{XXXXXXXXXXXXXXXXXXXXXXXX} 
\titlerunning{XXXXXXXX} % if too long for running head 
\maketitle 
\begin{abstract} 
  XXXXXXXXXXXXXXX
  \keywords{xx \and xxx \and xxx \and xxx \and xxxx \and xxx} 
\end{abstract} 
\section{Introduction}\label{sec:Introduction} 
 xxxxxxxx 
\section{Previous Work} \label{sec:PreviousWork} 
xxxxx
\end{document} % end of file
