use_tinytex() seems not to change the chosen directory

Dear @yihui ,

I installed tinytex to a specified directory. When executing use_tinytex() to make sure that the correct directory is used, it looks like everything works fine. I get the message:
"Restart R and your editor and check if tinytex::tinytex_root() points to J:/data/Documents/R/tinytex"

When I restart R and the editor (not only the session), tinytex_root() ouputs an empty string "". The directory that I chose ("J:/data/Documents/R/tinytex") seems to contain all installation files. But something prevents the change of the directory.

What can I do?

xfun::session_info('tinytex')
R version 4.2.3 (2023-03-15 ucrt)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 10 x64 (build 19044), RStudio 2023.3.0.386

Locale:
LC_COLLATE=German_Germany.utf8 LC_CTYPE=German_Germany.utf8 LC_MONETARY=German_Germany.utf8
LC_NUMERIC=C LC_TIME=German_Germany.utf8

Package version:
graphics_4.2.3 grDevices_4.2.3 stats_4.2.3 tinytex_0.44 tools_4.2.3 utils_4.2.3
xfun_0.31

tinytex::use_tinytex() will run tlmgr path add for you. If you got the line

"Restart R and your editor and check if tinytex::tinytex_root() points to J:/data/Documents/R/tinytex"

it means that the command succeeded. The command will modify your OS PATH environment variables. It should do it successfully if you have admin right or not. See command man page

Did you try restarting your computer ?

You can check if the PATH is added on Windows by running in Powershell

$env:PATH -Split ";" | Select-String "tinytex"

Or looking at your environment variable in Windows UI (a generic tutorial found online)

You can also try the following - If in PATH command should be found.

gcm tlmgr | Format-List

For customized installation to work with tinytex R package only (it won't put anything in your PATH), you can set this option for your R installation

options(tinytex.tlmgr.path="<path to the `tlmgr.bat` file>")

Hope it helps
