首先，我檢查了我的系統上是否安裝了這個軟體包：
✗ sudo tlmgr install exam
Password:
tlmgr: package repository https://mirrors.concertpass.com/tex-archive/systems/texlive/tlnet (verified)
tlmgr install: package already present: exam
當我pdflatex針對上述文件時，我遇到了未找到的錯誤exam.sty：
✗ pdflatex easy_questions.tex
This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020) (preloaded format=pdflatex)

這是否意味著該軟體包未安裝？我exam.sty從下載https://stuff.mit.edu/afs/athena/contrib/tex-contrib/Macros/exam.sty並將其複製到與我的乳膠源相同的目錄中。現在我收到另一個關於art11.sty未找到的錯誤：

我該如何修復這些錯誤？我認為安裝這個軟體包會非常簡單。
