tkz-euclide problem with \newcolumntype

Question

I'm trying to run a latex file by Stefan Kottwitz, it calls tkz-euclide:

% Circles in and around a triangle
% Author: Stefan Kottwitz
% https://www.packtpub.com/hardware-and-creative/latex-cookbook
\documentclass[border=10pt]{standalone}
\usepackage{tkz-euclide}
\usetkzobj{all}
\begin{document}
\begin{tikzpicture}
  \tkzDefPoints{0/0/A, 5/0/B, 1/4/C}
  \tkzDefCircle[in](A,B,C)
  \tkzGetPoint{M}
  \tkzGetLength{r}
  \tkzDefCircle[circum](A,B,C)
  \tkzGetPoint{N}
  \tkzGetLength{R}
  \tkzDefPointBy[projection=onto A--B](M)
  \tkzGetPoint{a}
  \tkzDefPointBy[projection=onto B--C](M)
  \tkzGetPoint{b}
  \tkzDefPointBy[projection=onto A--C](M)
  \tkzGetPoint{c}

  \tkzDrawCircle[R](M,\r pt)
  \tkzDrawCircle[R](N,\R pt)
  \tkzDrawPolygon[very thick](A,B,C)
  \tkzDrawLines[dotted](N,A N,B N,C)
  \tkzDrawLines[dashed](M,a M,b M,c)
  \tkzMarkRightAngles(M,a,B M,b,C M,c,C)
  \tkzDrawPoints(A,B,C,M,N,a,b,c)
  \tkzLabelPoints[below left](A,M,a,c)
  \tkzLabelPoints[below right](B)
  \tkzLabelPoints[above](C,b)
  \tkzLabelPoints[below](N)
\end{tikzpicture}
\end{document}

But I presented with and error.

I've dealt with this problem before, except this time I can't locate ./array.sty.

I apologise, that this isn't strictly a latex question.

Any suggestions?

Answer 1

The array package is a required part of the latex distribution so if you have latex at all you will have it.

However your log shows (./array.sty which means that you are not using the standard package but a copy in the same directory as your document this is a museum piece: an early version from 1990!! that predates LaTeX2e and predates \newcolumntype being added to the package. Simply delete the file in that directory and allow latex to find the standard one which will be in

/usr/local/texlive/2016/texmf-dist/tex/latex/tools/array.sty

on your system although you don't need that information, just that it will be found in the standard input path.
