What is the problem with compiling this tex file?

Question

This is a moderncv in Persian. I used to compile it smoothly but now I cannot. The error it says is as follows:

untitled-3.tex 15 Undefined control sequence. l.15 \cvtheme [blue]{bidiclassic}

\documentclass[11pt,a4paper]{bidimoderncv}

Answer 1

You need to check the availability of the selected fonts of the source file in the font directory of your operating system. In this case, Linux Libertine and XB Kayhan Sayeh must do exist in your system. In my case, I can simply substitute them with some other options like Times New Roman and XB Niloofar. Saying

\documentclass[11pt,a4paper]{bidimoderncv}

\usepackage{hyperref}
\usepackage{color}
\usepackage[numbers]{natbib}
\usepackage{xepersian}
\usepackage{pifont}

\cvtheme[blue]{bidiclassic}

\settextfont[Scale=1]{B Zar}
\setdigitfont{B Zar}
\setlatintextfont[Scale=1]{Times New Roman}
\defpersianfont\mytitlefont[Scale=.8]{XB Niloofar}
\AtBeginDocument{\recomputelengths} 

\firstname{\mytitlefont رضا}
\familyname{\mytitlefont فرزانه\newline\hspace*{10mm}}
\resumename{رزومه}
\title {\upshape \fontsize{0.5cm}{1em}\selectfont{} \hspace*{2mm}شرح حال }
\address
{\upshape  گروه فلسفه\\ دانشکده ادبیات\\ دانشگاه کرمان\\ تهران، ایران}
\mobile{091939870283} 
\extrainfo{\emailsymbol \emaillink{ [email protected]}}

\begin{document}
این رزومه متعلق به رضا فرزانه است.
\end{document}

applying XeLaTeX to the file yields a perfect compilation:
