I’m using OS X Catalina and Windows 10 in three different computers. Last R version 4.0.2 and last RSTUDIO version 1.3.1073 I install stan following the “ https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started ” Vignette instructions. I try to use the “schools.stan” example and I obtain “Er…

Hi Xavier, I can help troubleshoot your Windows installation, then we can tag someone to help with the Catalina installation. Can you run the following on your Windows machine and post the output: Sys.getenv("PATH") Sys.getenv("BINPREF") readLines("~/.R/Makevars.win") readLines("~/.Rprofile") rea…

On windows 10 computer: Sys.getenv(“PATH”) [1] “C:\estadistica\R\bin\x64;C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerS…

Thanks! It looks like you missed a step when installing RTools4: https://cran.r-project.org/bin/windows/Rtools/ Can you run: writeLines('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', con = "~/.Renviron") And then restart R/RStudio and try again?

writeLines(‘PATH=“{RTOOLS40_HOME}\usr\bin;{PATH}”’, con = “~/.Renviron”) Error: ‘\u’ used without hex digits in character string starting “'PATH=”${RTOOLS40_HOME}\u"

It looks like it didn’t copy correctly, you need the double backspace before the usr and bin paths (i.e. \\usr\\bin)

sm<-stan_model(model_code=sc) Warning message: In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) : ‘C:/ESTADI~1/rtools40/usr/mingw_/bin/g++’ not found fits<-sampling(sm, data=sd, chain=3) WORKS!!! Thanks

Great! That warning is safe to ignore. Let’s get someone to have a look at your Catalina installation(s) now! @jonah This user is on Catalina with R 4.0.2 and getting Error in unserialize(socklist[[n]]) : error reading from connection when running a model

[image] andrjohns: This user is on Catalina with R 4.0.2 and getting Error in unserialize(socklist[[n]]) : error reading from connection when running a model I’ve only seen rare instances of this on Mac. I think the most recent encounter with this error on Catalina was in the thread Some mode…

After some uninstall-install and reboot with yours recomentation WORKS in mac too!!! THANKS!!

Did you remove this? [image] jonah: -march=native
