Here is code I copied from official document. I got the following error.

\documentclass[12pt,letterpaper]{article}    
\usepackage[left=20mm,top=30mm,bottom=30mm,right=20mm]{geometry}
\usepackage[siunitx]{circuitikz} % circuit package and  include electrical units in our labels

\begin{document}


\begin{center}
\begin{circuitikz} \draw

(0,0) node[mixer] (m) {}
(m.w) to[short,-o] ++(-1,0)
(m.s) to[short,-o] ++(0,-1)
(m.e) to[short,-o] ++(1,0)
(m.w) node[inputarrow] {}
(m.s) node[inputarrow,rotate=90] {};


\end{circuitikz}
\end{center}


\end{document}

The error is the following

! Package PGF Math Error: Unknown function `w' (in 'w').

  • I get no error in texlive 2022. Show where you got the example, and your log with version numbers – David Carlisle Nov 28 '22 at 17:25
  • @DavidCarlisle I use textlive2019 – kile Nov 28 '22 at 17:32
  • and your example code comes from a 2019 document? – David Carlisle Nov 28 '22 at 17:39
  • @DavidCarlisle I am not sure. How can I find document for 2019? Any links? BTW, do you know how I can update my packages without re-installing textlive? – kile Nov 28 '22 at 17:42
  • You must know where you found it? In any case on overleaf it works on 2022 and 2021 but not 2020 or older. – David Carlisle Nov 28 '22 at 17:44
  • Unless you are very confident managing non-standard tex installs I would not install a new package in to texlive 2019, you are then in an un-tested, unsupportable configuration and quite likely to get further package conflicts from pgf or expl3 or siunitx or all of them. – David Carlisle Nov 28 '22 at 17:51
  • @DavidCarlisle Do you know where I can find manuals for 2019 circuitikz package? I have tried to find but no success. – kile Nov 28 '22 at 18:06
  • The contracted names for mixer anchors are new. Use west, north, etc. Or upgrade... https://tex.stackexchange.com/questions/524328/i-need-to-use-a-different-version-of-circuitikz-how-can-i-do-that – Rmano Nov 28 '22 at 18:24
  • All the versions of circuitikz with their manual and style files are here: https://circuitikz.github.io/circuitikz – Rmano Nov 28 '22 at 18:25

    you should have the manual on your machine, texdoc circuitikz – David Carlisle Nov 28 '22 at 18:29

I added the short form of the anchors on Apr, 18: https://github.com/circuitikz/circuitikz/pull/626/commits/71e4b3179c7e4d5cd6d61270854d31e74a2264ef, and fixed a bug with their positions with boxed elements.

So the easy solution for your installation is to use the long names: north, west, and so on.
