I am trying to install rstan on windows but run into multiple problems. Firstly, when I run
pkgbuild::has_build_tools(debug = TRUE) it returns
FALSE. Also, when I try to run the schools example
fit <- rstan::stan(file = '8schools.stan', data = schools_dat, chains = 4, iter = 10000, warmup = 5000), I get the following error:
Error in compileCode(f, code, language = language, verbose = verbose) : Compilation ERROR, function(s)/method(s) not created!

Anyone an idea what could be wrong?
