***********
使用我当前的 MiKTeX 2.9 和使用的类进行编译运行cas-sc.cls 2018/09/22, 1.0以以下错误消息结束：
! Undefined control sequence. \@begindocumenthook ...\@afterindentfalse \bibsep =0pt\gdef \bibfont {\fonts... l.89 \begin{document} The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined.
这表明该版本的类存在错误，需要维护者进行更正/重写。
根据我向您展示的已用包列表，您不需要调用例如包textcomp、等。graphicxamssymb
因为你没有告诉我们cas-sc你使用的是哪个版本的类，所以我无法告诉你如何更正这个有问题的类。最好的办法是请该类的维护者/所有者来更正它！
答案2
完整错误如下
! LaTeX Error: Option clash for package xcolor.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
大概是因为该类已经加载了xcolor，所以你可以删除
\usepackage[table]{xcolor}
有类似的错误
! LaTeX Error: Option clash for package amsmath.
