Error: ! kpathsea: Running mktexfmt pdflatex.fmt (or xelatex.fmt)... I can't find the format file pdflatex.fmt (or xelatex.fmt)

Hi Yihui,
I'm in panic. I have to submit my thesis in 3 weeks. I've been using bookdown the last 5 months because I have zero experience using latex. I struggle the first 2 months getting to the right format of my Uni using thesisdown and other packages, but I could only make it work using bookdown. The thing is I had an issue with a floating table (I never used tables in the rest of my thesis until this final chapter) and tried to solve it as per this yihui answer: https://stackoverflow.com/questions/44850011/how-to-stop-bookdown-tables-from-floating-to-bottom-of-the-page-in-pdf

When tried to apply kableExtra I got the "Remote repository newer than local". I followed yuhui advices and I used tinytex::reinstall_tinytex() and now tinytex is not correctly installed and not compiling the book.

When installing I got the messages in the following file:

tinytex_install_messages.txt
When trying to compile the book using build book I get this in the .log file:

! Running the command C:\Users\Ponchov\AppData\Roaming\TinyTeX\bin\win32\fmtutil-user.exe
! kpathsea: Running mktexfmt xelatex.fmt
! The command name is C:\Users\Ponchov\AppData\Roaming\TinyTeX\bin\win32\mktexfmt

changing to verbose output I get this, but don't know what they mean:

Running the command C:\Users\Ponchov\AppData\Roaming\TinyTeX\bin\win32\fmtutil-user.exe
I can't find the format file `xelatex.fmt'!

kpathsea: Running mktexfmt xelatex.fmt

The command name is C:\Users\Ponchov\AppData\Roaming\TinyTeX\bin\win32\mktexfmt
I was unable to find any missing LaTeX packages from the error log Tesis.log.
! Running the command C:\Users\Ponchov\AppData\Roaming\TinyTeX\bin\win32\fmtutil-user.exe

! kpathsea: Running mktexfmt xelatex.fmt

! The command name is C:\Users\Ponchov\AppData\Roaming\TinyTeX\bin\win32\mktexfmt

Aditionally I'm getting this message oftenly. This message is normal when installing tinytex, but now it shows up every time I hit build book:

Please help, I´m so closed to finish my thesis and I don´t think I´m able to rewrite it at this point.

Thanks,

Alfonso

To anyone who is still having problems with tinytex::install_tinytex(), please restart your R session, and try:

remotes::install_github('yihui/tinytex')
tinytex:::install_prebuilt()

This should work for Windows, macOS, and Ubuntu users.

I have tested tinytex::install_tinytex() on my local macOS, Windows, and Ubuntu, as well as on Travis and AppVeyor. Both the "missing pdflatex.fmt/xelatex.fmt or luatex.dll" and "gpg bad signature" issues are gone. If they are not on your machine, you probably need to wait for one more day or two till your CTAN mirror becomes up-to-date.

It seems a large update ;)

Haven't fully tested yet though, but thanks

Hola, tengo problemas al compilar un Rmarkdown, lo siguiente es lo que aparece al compilar un documento.
¿Me podrían ayudar a arreglar este error?, gracias.

Hi @Robert-Estiven ,

It is best if you ask your question on RStudio Community There is a broad community to help there, and isolate a potential issue.

If you think you found an issue, you can open a ticket in the correct GH repo.

From the error message you have, it seems you are using octave binary in a chunk and that the binary is not correctly found. It does not seem related with this ticket.

Happy to continue the discussion in the question you'll open in the RStudio community. Thank you !
