I recently discovered that I can use the dvisvgm engine to work in SVG presentations and have them play in my browser. So I found this new package animate here and I am attempting to have my own animations. But at least the doc of the PDF show the figures and everything, but no animations. I am using Chrome or Brave on a Fedora 31.

For example, I am attempting to reproduce the first example in the documentation (at p17 as of the doc version of 05.29.20), except that I get rid of the timeline option because I cannot quickly figure out how to generate a timeline.txt file (and the one used in the docs are not included in files).

\documentclass{article}
\usepackage{animate}
\usepackage{media9}
\usepackage{graphicx}
\begin{filecontents}{timeline.txt}
::0x0 % coordinate system & y=e^x, repeated until last frame
::1 % one blue curve per frame
::2
::3
::4
::5
::6
::7
::8
\end{filecontents}
\begin{document}
\begin{center}
\animategraphics[label=taylor,
                 controls, loop,
                ]{4}{exp_}{0}{8}
\mediabutton[jsaction={if(anim[’taylor’].isPlaying)anim[’taylor’].pause();else anim[’taylor’].playFwd();}
]{\fbox{Play/Pause}}
\end{center}
\end{document}

I tried to get use dvisvgm option either as optional argument of documentclass or of animate, and neither worked -- in the second case, the option is not recognized.

This is the error flow from the log file.

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.

Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.

A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

    Did you pass the correct option? \usepackage[dvisvgm]{animate} Also questions seeking debugging help (“why isn't this code working?”) must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. See minimal working example (MWE). – Henri Menke Jun 7 at 8:19
  • @HenriMenke Sorry, I extended my question, and provided essential details for reproducibility. – maurizio Jun 7 at 8:41
  • Have a look at this old question of mine tex.stackexchange.com/questions/404562/…, there might be useful information for you there – BambOo Jun 7 at 9:16
  • Your installation is broken. You have installed animate into your local texmf tree but you don't have the correct versions of the dependencies. Just update TeX Live as a whole to 2020. – Henri Menke Jun 7 at 9:28
  • @HenriMenke Thanks. Can you please point me out where you can deduce from the log above, that my installation is broken? It is just in the spirit of learning how to debug and read error messages more efficiently. – maurizio Jun 7 at 9:32
