Problems with rtools when installing RSTAN

[ca-signorelli]

Hei,
I am not able to install any of the programmes in the RSTAN family. It seems to be a problem with rtools, but it is not solved by deleting and reinstalling rtools40.

The Stan developer team tried to sort this out, but could not find the solution.
They directed me to this site.
Best regards

Just curious because I sometimes run into RStan issues myself - but the error message is reporting problems with jsonlite? Have you looked a bit into that problem so far?

I do vaguely remember some similar points popping up for me as well - but judging from the current state of my package library of my R-4.0.5 installation ...

options(mc.cores = parallel::detectCores()).
To avoid recompilation of unchanged Stan programs, we recommend calling
rstan_options(auto_write = TRUE)

which was build with Rtools40 - this seems to depend on your setup.

Do you maybe have something in your startup that loads (other) packages - loading packages from the tidyverse eg in your .Rprofile could have the effect that jsonlite updates (or installations) fail?

I think this is the background here. From here it seems jsonlite is being used as an example package that can be compiled from source.
