Hi, I am trying to install Rstan and verify whether it is successfully installed but I keep getting error message.

I used this code to install Rstan:  
install.packages(“rstan”, repos = c(“[Repository for distributing (some) stan-dev R packages | r-packages](https://mc-stan.org/r-packages/)”, getOption(“repos”)))

and when I try this:  
example(stan\_model, package = “rstan”, run.dontrun = TRUE)

I get the error message as following:  
Compilation ERROR, function(s)/method(s) not created!  
Error in compileCode(f, code, language = language, verbose = verbose) :
