So I am trying to draw barred arrow in tikzcd, and following the answer of for example here :https://tex.stackexchange.com/a/493140/236919 . It does not work because of marking. The other (much more complicated) solutions work for my problem
The minimal code is :
\documentclass{article}
\listfiles
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[]
a \arrow[r,"|" marking] & b
\end{tikzcd}
\end{document}
The expected result is : https://i.stack.imgur.com/ISB5L.png
Using pdfTeX, Version 3.14159265-2.6-1.40.18, I have the following warning :
! Package pgfkeys Error: I do not know the key '/tikz/marking' and I am going to ignore it. Perhaps you misspelled it.
See the pgfkeys package documentation for explanation. Type H for immediate help ... l.5 I think the culprit is a tikzcd arrow in cell 1-1. \errmessage ...currentrow -\tikzcd@currentcolumn } l.6 \end{tikzcd} ]
? H This error message was generated by an \errmessage command, so I can't give any explicit help. Pretend that you're Hercule Poirot: Examine all clues, and deduce the truth by order and method.
?
and the pdf produced is as follows:
the arrow is drawn, but the marking is ignored, thus the bar "|" is treated as a label and drawn above.
Could there be an issue with my pgfkeys package? I don't remember manually installing it, or how I installed latex/pdftex/..., but for what it's worth, I installed latex along TeXstudio 2.12.6 (hg 6631:16db084dae24)
Edit : after adding \listfiles to have the versions of my packages, here is a pastebin of the full log file :
I am not sure what to look for, but here is the result of $ grep Package: barred_arrow.log (plus some line breaks) :

etc... so probably simply your version has nomarking
option. You need to upgrade your LaTeX system.
