How to Resolve Compilation Error in “tcolorbox.sty” File

Question

I am trying to make a simple colorbox using the package tcolorbox but receiving a compilation error by just including the tcolorbox.sty file.

Please consider the following code:

%\documentclass[12pt]{article}
\documentclass[dvipsnames,cmyk]{article}

% File Containing All the Control Settings
\usepackage{../../Style/mystyle}
\usepackage{../../Style/tcolorbox/tcolorbox}    ---> This line is giving compilation Error
\usetikzlibrary{matrix}
\begin{document} 

\end{document}

Compilation Error:

! Paragraph ended before \pgfkeys@@qset was complete.

The Offending lines in the tcolorbox.sty file are:

parskip/.style={before={\par\pagebreak[0]\noindent},after={\par}},
noparskip/.style={before={\par\smallskip\pagebreak[0]\noindent},after={\par\smallskip}},

Please guide me how to resolve this error.

Answer 1

matrix causes the error. Try this MWE (compiling with no errors), then delete the % and compile again.

MWE:

\documentclass[dvipsnames,cmyk]{article}
\usepackage{tcolorbox}
%\usetikzlibrary{matrix}
\begin{document} 
test

\begin{tcolorbox}[colback=red!5,colframe=red!75!black]
  My box.
\end{tcolorbox}
\end{document}
