TeX Live and MacTeX ⇒ Error message in WebQuiz

[Boczko]

Hi All, this is my first time posting a question. I have been using TeXShop for a long time and TeX for longer. I am proficient in LaTeX but I am not a developer or a TeXPert.

I teach math and I am creating an online course. I discovered WebQuiz and it would be perfect for me. I appreciate Andrew Mathas and the university of Sydney for writing this package and making it available. I just downloaded the 2019 TeXlLive distribution to be able to use the WebQuiz package.

When I compile my test file with pdfTeX the output all looks fine. When I compile with

> webquiz testing.tex I get this error

This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019) (preloaded format=pdflatex)

Hi Boczko,

welcome to the forum!

There was an error in the pgf package causing such a message, that has been fixed. Try if you can update the pgf package using tlmgr, the TeX Live Manager.

Otherwise, try adding \usepackage{pgf} to ensure it's loaded.
