I wanted to use the chemfig package and installed it using tllocalmgr in arch Linux. However when I tried to use pdflatex on a tex file like this one,

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\usepackage{chemfig}


\usepackage{geometry}
\geometry{textwidth=8cm}

\section{Introduction}


%Simplest working example example
%----------------------------------------------------------
Writting chemical formulae with chemfig is straightforward.


\chemfig{O=H}
%----------------------------------------------------------
\vspace{1cm}


%Angles between bonds
%----------------------------------------------------------
To define chemical formulae you can use units that define the angles


\chemfig{A-[1]B-[7]C}


Absolute angles


\chemfig{A-[:50]B-[:-25]C}


Relative angles


\chemfig{A-[::50]B-[::-25]C}
%----------------------------------------------------------


\vspace{1cm}


%Rings
%----------------------------------------------------------
Regular polygons


\chemfig{A*5(-B=C-D-E=)}


Incomplete rings are also possible


\chemfig{A*5(-B=C-D)}
%----------------------------------------------------------
\clearpage


%Branched molecule
%----------------------------------------------------------
Branched molecule \vspace{.5cm}


\chemfig{H-C(-[2]H)(-[6]H)-C(=[1]O)-[7]H}
%----------------------------------------------------------


\vspace{1cm}
%Branched ring
%----------------------------------------------------------
Branched ring
\vspace{.5cm}


\chemfig{A*6(-B=C(-CH_3)-D-E-F(=G)=)}


%----------------------------------------------------------


\vspace{2cm}


%Personalized parameters
%----------------------------------------------------------
{\huge 
    \setchemfig{atom sep=2em,bond style={line width=1pt,red,dash pattern=on 2pt off 2pt}}

    \chemname
    {\chemfig{H-C(-[2]H)(-[6]H)-C(=[1]O)-[7]H}}
    {Ethanal}
}
%----------------------------------------------------------


\end{document}

it gave the following error :

! Undefined control sequence.
l.362 \defKV
        [chemfig]{%
?

and the pdf output was weird :

pdf output

I am new to latex and I mostly use it in Org-mode (emacs) and I noticed that it's pdf output was not correct when I used chemfig so I decided to run pdflatex myself and saw these errors. I have TeX 3.14159265 (TeX Live 2019/Arch Linux)

Edit: here is pdflatex's log file

log :

  • It is preferable not to use the distro package manager to install LaTeX – Alessandro Cuttin Jun 17 '20 at 12:18
  • @AlessandroCuttin tlmgr is broken in arch linux and even fix doesnt work. I tried installing manually as described here but even that didn't work. here is pdflatex's log (updated in the answer as well) – Nilaksh Singh Jun 17 '20 at 13:14
  • Or use upstream TL (tug.org/texlive) instead of what ever it is arch is providing. Also we generally do not like going to external sites for code or logs as external links rot over time and thus your question will not be usable for others. – daleif Jun 17 '20 at 13:24
  • @daleif I have updated the question as per your suggestion. – Nilaksh Singh Jun 17 '20 at 13:45
  • No issues using Upstream TL2020 on Ubuntu. – daleif Jun 17 '20 at 13:54
  • Additionally also compiles using my frozen (no more updates) upstream TL2019. – daleif Jun 17 '20 at 13:59

    \defKV is defined by the simplekv package. Your log shows that it is loaded so my guess is that your version of said package is outdated... – cgnieder Jun 17 '20 at 15:38
  • @cgnieder This is weird because I just installed all the packages and texlive few days ago. Anyway manually updating simplekv fixed the issue. Thank you and Sorry for causing trouble. – Nilaksh Singh Jun 17 '20 at 15:50

I updated the package simplekv using tllocalmgr and while that fixed the problem with chemfig, I was still getting errors with other packages so I uninstalled Arch's texlive installation and instead used an upstream installer. After doing this everything works perfectly and even tlmgr works.

So the answer would be to not use distro's package manager.
