Hello! I suddenly began running into an issue with running models using brms. The code below worked fine last week, but after updating my R packages this afternoon (04/12/21), I began receiving the following error when attempting to run any model with brms.
> library(brms)
Loading required package: Rcpp
Loading 'brms' package (version 2.15.0). Useful instructions
can be found by typing help('brms'). A more detailed introduction
to the package is available through vignette('brms_overview').
Attaching package: ‘brms’
The following object is masked from ‘package:stats’:
ar
> prior1 <- prior(normal(0,10), class = b) +
+ prior(cauchy(0,2), class = sd)
> fit1 <- brm(count ~ zAge + zBase * Trt + (1|patient),
+ data = epilepsy, family = poisson(), prior = prior1)
Compiling Stan program...
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared object 'C:/Users/JASON_~1/AppData/Local/Temp/RtmpKE1VuQ/file1fc44c4653fb.dll':
LoadLibrary failure: A dynamic link library (DLL) initialization routine failed.
In addition: Warning message:
In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
'C:/rtools40/usr/mingw_/bin/g++' not found
Error in sink(type = "output") : invalid connection
I have searched far and wide in terms of potential solutions (e.g., reinstalling relevant packages, uninstalling and reinstalling R and RStudio, etc.), but the error persists. I am able to run models in rstanarm with no issue.
I would greatly appreciate any guidance towards a solution.
