'Error : File `l3backend-pdfmode.def' not found. }

I am trying to compile a .tex document into a pdf in TexStudio (and I have also tried in MikTex) and the following error is outputted File l3backend-pdfmode.def not found. I have tried downloading 13backend package but no luck. Do I need to place the package in a specific folder?

latex tex miktex

I had the same problem, turned out my miktex library was out-of-date

I opened "miktex console" and updated it.

Solution 2:^[2]

I incurred into the same issue slightly after an upgrade from Debian 10 to Debian 11. For me, removing all the .texlive* directories from my home folder solved it

mv ~/.texlive* /tmp # If you want to restore them later
rm -r ~/.texlive* # If you are sure about deleting

The ~/.texlive2020 directory was rebuilt after running pdflatex.
