[Message part 1 (text/plain, inline)]

Related to [1]. Reproducing:

   guix environment -C --pure --ad-hoc r r-readr
   Rscript -e 'library(readr); default_locale()'

A hack that fixes this issue is to include tzdata among the environment
inputs, and to set

   TZDIR=/gnu/store/$(ls -F /gnu/store | grep tzdata.*/ | head -n 1)share/zoneinfo

(actually, one needs also coreutils and grep to do that, but that’s
beyond the point). I haven’t tried it (yet?), but maybe it suffices to
add tzdata to r-readr inputs in the package definition to fix this
issue.

The output is:

--8<---------------cut here---------------start------------->8---
Error: Unknown TZ UTC
In addition: Warning message:
In OlsonNames() : no Olson database found
Execution halted
sh: rm: command not found
--8<---------------cut here---------------end--------------->8---

Just adding tzdata to the propgapated-inputs list is not enough.


Well, I do not understand why the test suite pass. It should fail if
locale date is required... I am missing a point. Especially when
reading these 2 comments:

https://github.com/tidyverse/readr/issues/952#issuecomment-451255375

Let investigate more...


Thank you for the report.
All the best,
simon
