debugging rmarkdown error 'tlmgr' not found

Question

I'm trying to knit to PDF using an .rmd file. It failed and suggested I look:

https://yihui.org/tinytex/r/#debugging for debugging tips.

The second step is to run tinytex::tlmgr_update(), however this returns:

tlmgr update --all --self

Error in system2("tlmgr", args, ...) : '"tlmgr"' not found

How should I proceed?

Answer 1

I would try running:

tinytex:: install_tinytex()

then try running:

update.packages(ask = FALSE, checkBuilt = TRUE)
tinytex::tlmgr_update()

Answer 2

Try tinytex:::install_prebuilt(). I found this solution that worked for me at https://community.rstudio.com/t/cannot-install-tinytex/129302
