I am using TeX 3.14159265 (TeX Live 2019/Debian). My simple test code is:

\documentclass[]{article}
\usepackage{nicematrix}

\begin{document}


\section{}
\begin{NiceTabular}{@{}c!{\qquad}ccc!{\qquad}ccc@{}}
    \toprule
    & \Block{1-3}{First group} & & & \Block{1-3}{Second group} \
    Rank & 1A & 1B & 1C & 2A & 2B & 2C \
    \midrule
    1 & 0.657 & 0.913 & 0.733 & 0.830 & 0.387 & 0.893\
    2 & 0.343 & 0.537 & 0.655 & 0.690 & 0.471 & 0.333\
    3 & 0.783 & 0.885 & 0.015 & 0.306 & 0.643 & 0.263\
    4 & 0.161 & 0.708 & 0.386 & 0.257 & 0.074 & 0.336\
    \bottomrule
\end{NiceTabular}
\end{document}

This gives me:

! LaTeX Error: Environment NiceTabular undefined.

The version of nicematrix is 2020/02/07 v3.11

Is there any way to use nicematrix with Tex Live 2019?

  • nicematrix expects latest version of latex3 supporting files, better to update your package manager and then try... – MadyYuvi Aug 17 '20 at 10:50
  • @MadyYuvi This is the latest version that ubuntu 20.04 gives you and that is the latest version of ubuntu. – Simd Aug 17 '20 at 10:54

    NiceTabular is a rather new environment added in nicematrix 2020/05/08 v4.0, see the corresponding announcement text. You need to either use old environments or upgrade nicematrix or the whole latex distribution. – muzimuzhi Z Aug 17 '20 at 10:57
  • @muzimuzhiZ what is the cleanest way to upgrade nicematrix without upgrading the whole latex distribution? – Simd Aug 17 '20 at 11:01
  • Tex Live Package Manager. – Bernard Aug 17 '20 at 11:19
  • @fomin Manually installation. nicematrix consists of a single nicematrix.sty file which you can download from texlive's svn repo. If newer version of nicematrix relies on any new codes from its dependencies, the whole process will be much much harder. – muzimuzhi Z Aug 17 '20 at 11:37
  • Alternatively, you can follow the steps in https://www.tug.org/texlive/upgrade.html to upgrade from texlive 2019 to 2020 without a new installation. – muzimuzhi Z Aug 17 '20 at 11:44
  • @Bernard I just tried it. There seems to be a bug https://tex.stackexchange.com/questions/528634/tlmgr-unexpected-return-value-from-verify-checksum-5 which has suggested workarounds that I am trying to get to work. – Simd Aug 17 '20 at 12:07

    I have put the file latest version of nicematrix.sty (5.1) here : (https://pastebin.pl/view/b9780ffe). It works with TeXLive 2019. You put that file in the reportory of your document and that's all. – F. Pantigny Aug 17 '20 at 17:58
  • @F.Pantigny Thank you so much! The link doesn't seem to work though. It just hangs for me. – Simd Aug 18 '20 at 10:29
  • @fomin: Yes. There is a problem. If you want, send me a mail (fpantigny@wanadoo.fr). I will send you the file. – F. Pantigny Aug 18 '20 at 11:08
  • Just copying nicematrix.sty does seem to work. Thank you. – Simd Sep 24 '20 at 13:54
