Package siunitx Error: Package 'units' incompatible

[biochem-birmingham]

I've been using siunitx successfully with the Tufte book class for a couple of years, but now my .tex file doesn't compile. To make a minimal example, I took the sample-book.tex file from these github pages (compiles ok), but when I add "\usepackage{siunitx}" anywhere before \begin{document}, and no other lines or latex code, the sample-book.tex no longer compiles. I don't know enough about the Tufte book class and .sty files to see where the clash is. Any suggestions for a way forward?

Have tried with Ubuntu and Windows versions of TexStudio (default installation options). Miktex packages are up to date.

many thanks in advance

I have the same problem, does anybody have a solution?

I wasn't able to wait for a solution to this (had to meet a fixed deadline), so I migrated to the KAO Book Latex Template. While I did find the Tufte book template very useful for several years, I am pleased to have made the transition to KAO Book. So far, a good experience and no issues with siunitx. Also, usage of \label and \ref to specific sections and figures has been more successful for me in KAO Book.

Thanks for the answer, I hope there is a other solution to get this solved. Unfortunately, changing the template is currently not an option for me.

See in the siunitx documentation the section "Upgrading from version 2".
