Abaixo está um MWE do meu documento látex que usa a examclasse.

\documentclass{article}
\usepackage{exam}
\renewcommand{\choicelabel}{(\thechoice)}

\begin{document}

\begin{questions}
\question
This is question 1
\begin{choice}
\choice green
\choice blue
\choice yellow
\choice orange
\end{choice}
\\
\question
This is question 2
\begin{choice}
\choice 6
\choice 7
\choice 8
\choice 9
\end{choice}
\\
\end{questions}
\end{document}

Primeiro, verifiquei se este pacote estava instalado no meu sistema:

✗ sudo tlmgr install exam    
Password:
tlmgr: package repository https://mirrors.concertpass.com/tex-archive/systems/texlive/tlnet (verified)
tlmgr install: package already present: exam

Quando pdflatexencontrei o arquivo acima, encontrei um erro exam.stynão encontrado:

✗ pdflatex easy_questions.tex

Isso significa que o pacote não está instalado? eu baixei exam.stydehttps://stuff.mit.edu/afs/athena/contrib/tex-contrib/Macros/exam.stye copiei-o para o mesmo diretório da minha fonte de látex. Agora recebo outro erro sobre art11.stynão encontrado:

Como posso corrigir esses erros? Achei que seria bastante simples instalar este pacote.
