[Tex/LaTex] Problem with chemmacros, beamer and filehook-scrlfile.sty

beamerchemmacrosfilehookkoma-script

I am using chemmacros with beamer and it produces the following error

2017/08/28 basic chemmacros module
(/usr/local/texlive/2019/texmf-dist/tex/latex/koma-script/scrlfile.sty
Package: scrlfile 2019/10/12 v3.27 KOMA-Script package (loading files)

! Package filehook Error: Detected 'scrlfile' package with unknown definition o
f \InputIfFileExists.
Use the 'force' option of 'filehook' to overwrite it..
See the filehook package documentation for explanation.
Type H for immediate help.

If I comment out chemmacros or use a different documentclass to beamer there is no error.

Can anyone shed any light on this?

While I do get a usable output it is disconcerting to see an error coming up in the compilation and I am not sure if it will cause a fatal output in different usage of chemmacros . Is this a bug in KOMA-script as I believe it was recently updated but chemmacros wasn't.

\documentclass{beamer}
\usepackage{chemmacros}

The problem has been resolved by an update of the sansmathaccent package. It now no longer uses the filehook package.

[Tex/LaTex] Beamer themes cannot be found / Ubuntu / I’ve tried every folder one can imagine

run in a terminal:

kpsewhich beamerthemedefault.sty

and you'll get the exact position of that file. However, that is the official directory, where personal files schould not go. There is an local texmf tree. You can get that directory by running

kpsewhich -var-value TEXMFLOCAL

On my system I'll get

/usr/local/texlive/texmf-local

In that directory create a subdirectory like

mkdir -p /usr/local/texlive/texmf-local/tex/latex/beamer/

and put your personal file in there. Then run texhash from the command line to update the data base. A following

kpsewhich beamerthemeAmsterdam.sty

should give the complete path.

You should NOT put custom or personal additions under /usr/local/texlive/2013/ as that directory should be reserved for the TeX distribution. Changes you make there can easily be overwritten when you update the installation and will certainly be lost if you switch to, say, TeX Live 2014.

The reason it doesn't work when you add the theme there is because TeX relies on a database of hashed names to find things in that directory. You would have to also update that database in order for the theme to be found.

You have two options.

Your personal texmf tree. TeX does not use a hashed database to search this directory - it just looks at what is there at the time of compilation.
/usr/local/texlive/texmf-local/ [note that this is NOT under a directory named for a year]. TeX does use a hashed database for this directory. So if you use this one, you need to update that database in order for the theme to be found.

The first option is easier since all you need do is put the file in the correct place - no need to worry about updating any database.

Try placing the theme in <your home directory>/Library/texmf/tex/latex/beamer/themes/ to mirror the directory structure you found in your main texmf tree. Note that you should NOT use /Library. You want to use <your home>/Library/.

If you did want to use the local texmf tree rather than your personal one - perhaps because other users of the machine should have access to the same theme - you could use /usr/local/texlive/texmf-local/tex/latex/beamer/themes/. To update the database of names, you would then need to run mktexlsr /usr/local/texlive/texmf-local. (You could just run mktexlsr but it is a little quicker to specify the appropriate texmf tree.)
