tinytex/tlmgr WIPING the entire installation

[r-cheologist]

This bug report here is difficult, as I have a hard time reproducing it. I have reported this already here: https://stackoverflow.com/q/61226226/2103880 - at least one other person has similar problems.

What I'm seeing (with both the released and remotes::install_github("yihui/tinytex") version) in essence is

1. tinytex installs just fine
2. Processing of *.tex file starts out properly and required packages are being pulled in from CTAN as expected
3. Irreproducibility creeps in here: at some point during the installation of dependencies (reproducible in effect but NOT in number of packages pulled in, nor associated with defined packages), tinytex fails installation and
4. the entire ~/.TinyTeX directory is REMOVED from the file system

If any package install fails (for example due to a given mirror not being up to date with the ungoing TeXLive 2020 release), I would expect the process to fail (possibly with a failover to another mirror), but leaving me with the tinytex installation present to try again.

Here's my attempt at a "reproducible" example:

> tinytex::install()
<... LOTS of output ... NO errors/warnings>
TinyTeX installed to /home/rstudio/.TinyTeX
You may have to restart your system after installing TinyTeX to make sure ~/bin appears in your PATH variable (https://github.com/yihui/tinytex/issues/16).

Installing tinytex_0.21.3 from here does NOT fix the issue.

Hi, I'm having the same issue. My previous installation basically disappeared and I don't know why. Trying to reinstall either the tinytex_0.21 or tinytex_0.21.3 does not solve the problem. Installing the prebuilt using `tinytex:::install_prebuilt()" also fails.

Here is my session info

Sounds like a very nasty bug. I'll look into it right now. Sorry about that!

[raphael-gouvea]

Thanks Yihui!
I also tried to install using the terminal following instructions on the website. No success also in this way.

[yihui]

My bad! Should be fixed now. Please test remotes::install_github('yihui/tinytex'). Thanks a lot for the report! I'll make a CRAN release as soon as possible.

[yihui]

I forgot to mention you only need to install the dev version of the R package tinytex. No need to reinstall TinyTeX.

[r-cheologist]

Installation now works indeed and needed CTAN packages are pulled in, but after that I continue to get:

> tinytex::pdflatex("<MYFILE>.tex")
This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020) (preloaded format=pdflatex)
restricted \write18 enabled.
entering extended mode
I was unable to find any missing LaTeX packages from the error log Graumann_CurriculumVitae.log.
! LaTeX Error: This NFSS system isn't set up properly.

Error: LaTeX failed to compile <MYFILE>.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See Graumann_CurriculumVitae.log for more info.

startpaging(googleing) does not appear to help here ... what may be wrong now?

[r-cheologist]

Forget it - this apparently is related to me trying to use the textgreek package. Sorry for the noise.

[yihui]

No worries. Thanks a lot for testing it!

[raphael-gouvea]

It works for me too. Thanks a bunch @yihui!
