tkz-euclide "Undefined control sequence"

Question

I've been trying to practice tkz-euclide by working through the documentation's examples. But I've been getting errors. Here:

\documentclass{article}
\usepackage{xcolor}
\usepackage{tkz-euclide}
\usepackage{beton}
\usepackage{euler}

\begin{document}
    \begin{tikzpicture}
    \tkzDefPoints{0/0/A,4/0/B}
    \tkzDrawLine[red](A,B)
    \tkzDefPointOnLine[pos=1.2](A,B)
    \tkzGetPoint{P}
    \tkzDefPointOnLine[pos=-0.2](A,B)
    \tkzGetPoint{R}
    \tkzDefPointOnLine[pos=0.5](A,B)
    \tkzGetPoint{S}
    \tkzLabelPoint[above](P){pos=$1.2$}
    \tkzLabelPoint[above](R){pos=$-.2$}
    \tkzLabelPoint[above](S){pos=$.5$}
    \tkzDrawPoints(A,B,P,R,S)
    \tkzLabelPoints[](A,B)
\end{tikzpicture}
\end{document}

When I try to compile this I get this error despite the command being listed and used in the documentation:

Undefined control sequence. [\tkzDefPointOnLine]

I've checked similar questions, but they all say to add usetkzobj{all} and yet the current README of the package says this is not required. Furthermore, when I do add it in, I get this:

I can't find file `tkz-obj-angles.tex'. [\usetkzobj{all}]

What's going on?

Answer 1

The issue is due to using an old version of tkz-euclide (check Allain Matthes comment on the question for more details)

With the correct version, you should get the following image:
