首先，我检查这个包是否安装在我的系统上：
✗ sudo tlmgr install exam
Password:
tlmgr: package repository https://mirrors.concertpass.com/tex-archive/systems/texlive/tlnet (verified)
tlmgr install: package already present: exam
当我pdflatex针对上述文件时，遇到exam.sty未找到错误：
✗ pdflatex easy_questions.tex

这是否意味着该软件包未安装？我exam.sty从https://stuff.mit.edu/afs/athena/contrib/tex-contrib/Macros/exam.sty并将其复制到与我的 latex 源相同的目录中。现在我收到另一个art11.sty未找到的错误：

我该如何修复这些错误？我以为安装这个包会很简单。
