Hi everybody,

After an update I got the following error:

Error: Failed to compile Informe3EP-knitr.tex.
In addition: Warning message:
running command '"pdflatex" -halt-on-error -interaction=batchmode "Informe3EP-knitr.tex"' had status 1

Any ideas how to fix the problem?
Thanks a lot for any suggests.
Ana

A recent version of rmarkdown changed how it calls LaTeX and pandoc (I believe it was something where the call to LaTeX used to be indirect through pandoc, but now is done more directly). This also caused this type of problem for me, at least when using rmarkdown::render (as opposed to the 'knit' button)

See the extended discussion of the issue here:

R markdown does not create a pdf file

Hi, When I try to knit the vanilla example Rmd file to "pdf" I get the below …error. I tried re-installing the packages and restarting the R session several time but it dint help. Output created: test.pdf Error in tools::file_path_as_absolute(output_file) : file 'test.pdf' does not exist Calls: <Anonymous> -> <Anonymous> In addition: Warning messages: 1: running command '"pdflatex" -halt-on-error -interaction=batchmode "test.tex"' had status 1 2: In readLines(logfile) : incomplete final line found on 'test.log' Execution halted

Two things that helped me:

Make sure your all your paths do not have spaces. In particular, my LaTeX engine (MiKTeX) used to be located in a path with a space, but when I switched it to a path without, it was fixed.
Update Rstudio to a recent version.

I am a little unclear if it has been resolved in knitr/markdown packages, but this Rstudio issue was also affecting pdf creation on windows for me:

system2('pdflatex', stdout = FALSE) fails on Windows (only with MiKTeX in RStudio)

bug

### System details RStudio Edition : Desktop RStudio Version : 1.1.4…42 OS Version : Windows 7 R Version : 3.4.3 ### Steps to reproduce the problem Install MiKTeX: https://miktex.org/download Compile this minimal example `test.tex` in the R console in RStudio via `system2('pdflatex', 'test.tex', stdout = FALSE)`: ```tex \documentclass{article} \begin{document} asdf \end{document} ``` ### Describe the problem in detail Compilation fails, with a warning message `running command '"pdflatex test.tex"' had status 1`. ### Describe the behavior you expected It should generate `test.pdf`. Note that 1. `system2('pdflatex', 'test.tex')` succeeds (i.e. with the default `stdout = ""`). 2. In the default R GUI on Windows (not using RStudio), `system2('pdflatex', 'test.tex', stdout = FALSE)` succeeds, which indicates this issue is likely to be specific to the R console in RStudio (redirecting stdout fails in certain cases?). It also succeeds in the Terminal in RStudio. 3. Other LaTeX distribution such as TeX Live also fails with `stdout = FALSE` on Windows in RStudio. However, TeX Live succeeds with `system2('pdflatex', c('-halt-on-error', '-interaction=batchmode', 'test.tex'), stdout = FALSE)`, but MiKTeX still fails with these extra arguments. This issue affects rendering R Markdown to PDF on Windows in the R console in RStudio. Several users have reported the issue over the past few days (e.g. https://github.com/rstudio/rmarkdown/issues/1285) and I just figured out the root reason (thanks to the hint by @shrektan https://github.com/yihui/tinytex/issues/28).

Thanks so much for the comments.

Now it´s working

Hello Ana, can you tell what you did (following jalsalam pointers) that solved it? Was it removing the space from the path where the tex program is stored? Was it simply updating Rstudio?

Thanks in advance.

Hi Omar,

What i did was rename my MikTex folder in programs and after that in RStudio I installed the package tinytex again(devtools::install_github('yihui/tinytex')
After these two steps it worked again
You can see more information here: https://github.com/rstudio/rmarkdown/issues/1285
I hope this help you

Hi Ana,

Thanks for the further detailsn since they were of good help. Installing the package tinytex and restarting R did the trick for me this time. I also removed the spaces from the path where miktex engine was stored.

Hope this also help others.
