Error when using tinytex::install_tinytex - missing argument in paste0

[tbradley1013]

Hi,

I was trying to install TinyTex this morning via tinytex::install_tinytex and ran into a weird error. I got the same error from both the current CRAN release (0.7) and the current devel version. Here is the error:

> tinytex::install_tinytex()

Starting to install TinyTeX to C:\Users\Tyler.Bradley\AppData\Roaming/TinyTeX. It will take a few minutes.
Error in paste0("Next you may see two error dialog boxes about the missing luatex.dll, ",  : 
  argument is missing, with no default
Please restart your R session and IDE (if you are using one, such as RStudio or Emacs) and check if tinytex:::is_tinytex() is TRUE.

As expected, given the error message, when I restarted my R and Rstudio session tinytex:::is_tinytex() returned FALSE. I looked through the source code and it looks like the issue is here. I am not entirely sure what is causing the issue, since I don't see any issues with the paste0 call. However, this was the only thing stopping the installing. I ran debug(tinytex::install_tinytex()) and ran everything but those few lines and it looks like TinyTex installed properly. After restarting my session, tinytex:::is_tinytex returned TRUE.

I thought it was worthwhile to report this, as I am not sure whether other people have run into this before.

Thanks for the great packages!

As a follow up, once I tried to knit a document after installing TinyTex, I get the following error:

Error: Failed to compile low-dbps-q2-2018-report.tex.
In addition: Warning message:
In system2(..., stdout = FALSE, stderr = FALSE) : '"pdflatex"' not found
Execution halted

No TeX installation detected (TeX is required to create PDF output). You should install a recommended TeX distribution for your platform:

  Windows: MiKTeX (Complete) - http://miktex.org/2.9/setup
  (NOTE: Be sure to download the Complete rather than Basic installation)

  Mac OS X: TexLive 2013 (Full) - http://tug.org/mactex/
  (NOTE: Download with Safari rather than Chrome _strongly_ recommended)

  Linux: Use system package manager

I thought it might be a PATH issue so I added the output of tinytex:::texlive_root() to my PATH and it still produced the same error.

I am not sure whether this has to do with how I did the installation or not. Any help would be greatly appreciated.

Sorry about that. There was an extra comma in paste0(). I just fixed it. You can use either the current development version or tinytex:::install_prebuilt().

The PATH issue should not exist if you restart RStudio after installing TinyTeX.

Thanks @yihui ! After reinstalling the development version and rerunning the function the installation works correctly. I guess the installation wasn't complete when I ran the function with debug.

Thanks for taking care of this so quickly!

Hi @yihui, I am also having the same problem while knitting to a PDF. I used all the debugging steps mentioned on your website. I am getting the following error. I tried to uninstall and reinstall it but I am getting the same error. I am using R4.0. Could you please tell me how can I fix it? Thanks.

When I am running tinytex::tlmgr_path() command I am getting following error:
Use of uninitialized value in bitwise or (|) at C:\Users\Javed\AppData\Roaming\TinyTeX\texmf-dist\scripts\texlive\tlmgr.pl line 1497.

Hi @yihui can you please help with my error I am getting similar error can you please look into that.

Error in aperm.default(map, c(2, 1, 3)) :

Calls: ... eval -> get_map -> get_googlemap -> aperm -> aperm.default
In addition: Warning message:

No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: https://www.latex-project.org/get/

If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()

Otherwise consider MiKTeX on Windows - http://miktex.org

MacTeX on macOS - https://tug.org/mactex/
(NOTE: Download with Safari rather than Chrome strongly recommended)

Linux: Use system package manager

@virtiparekh That's the error. I don't see how this error is similar to the one in the original post above. It looks like a completely different error and is unlikely to be relevant to tinytex.

If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()

Have you done what the message suggested you do?
