Error by using tcolorbox for own style boxed text creation

My code follows:

documentclass{book}
usepackage{tcolorbox}%
begin{document}

begin{tcolorbox}[enhanced, title=Mytitle, attach boxed title to top
center={yshift=-3mm,yshifttext=-1mm},boxed title
style={size=small,colback=blue}]
This is my own box with a mandatory title
and options.
end{tcolorbox}

end{document}

While running LaTeX, some error are coming, I’ve pasted the log file below:
