环境：
Windows 10 (x64)；
MiKTeX 2.9.7206-x64、GPL Ghostscript 9.25（2018-09-13）
共享 TeX 安装；
'animate' 包 2019/08/22；
'dvisvgm' 2.6.3（来自 MiKTeX 的实用程序）；
2017/06/20 v1.0b dvisvgm 用于 latex 的图形驱动程序（C:\Program Files\MiKTeX 2.9\tex\latex\graphics-def\dvisvgm.def）
我正在尝试从手册中编译一个例子亚历山大·格拉恩：
\documentclass{article}
\usepackage{intcalc} %defines \intcalcMod for Modulo computation
\usepackage{animate}
\usepackage{graphicx}
\graphicspath{{files/}}
\newcounter{scarab}
\setcounter{scarab}{0}
\newcounter{blueline}
\setcounter{blueline}{101}
\newcounter{grayline}
\setcounter{grayline}{202}
%write timeline file
\newwrite\TimeLineFile
\immediate\openout\TimeLineFile=scarab.tln
\whiledo{\thescarab<101}{
\ifthenelse{\intcalcMod{\thescarab}{2}=0}{
%a gray line is added to every 2nd frame
\immediate\write\TimeLineFile{%
::\thegrayline x0;253;\thescarab x0,\theblueline}
\stepcounter{grayline}
}{
\immediate\write\TimeLineFile{%
::;253;\thescarab x0,\theblueline}
}
\stepcounter{scarab}
\stepcounter{blueline}
}
\immediate\closeout\TimeLineFile
%\DeclareGraphicsRule{.mps}{eps}{*}{}
\begin{document}
\begin{center}
\animategraphics[width=0.8\linewidth,
autoplay,controls,loop,timeline=scarab.tln]{12}{scarab_}{0}{253}
\end{center}
\end{document}
此源文件可以转换为 PDF 文件，无需选项“韋斯維爾' 无论如何，即 'pdflatex' 或 'latex' ---> 'dvips' ---> 'ps2pdf'。结果是好的。但在添加此选项后（在 '\documentclass[12pt,韋斯維爾]{article}') 构建 DVI 文件变得不可能（命令行：latex文件.tex):
! LaTeX Error: Unknown graphics extension: .mps.
l.35 ...ine=scarab.tln]{12}{scarab_}{0}{253}
如果我插入
\DeclareGraphicsRule{.mps}{eps}{*}{}
编译中止，原因如下：
! Undefined control sequence.
\pbs_pdflastann: ->\g_pbs_pdflastann_tl
l.35 ...ine=scarab.tln]{12}{scarab_alter_}{0}{253}
如果没有选项 'divsvgm'，则实用程序韋斯維爾仅从 DVI 创建单个 svg 文件。
它说这里通过更新 TeXLive 安装，类似的问题已经得到解决。
我想知道是否有人可以具体说明需要在 MiKTeX 中更新哪些内容才能消除此错误。
