Unable to install Rstan

Hi all,

I had some difficulties when I was trying to install Rstan. When I try the following code:

# Compile packages using all cores
Sys.setenv(MAKEFLAGS = paste0("-j",parallel::detectCores()))

install.packages(c("StanHeaders","rstan"),type="source")

I got the output:

But when I verify my installation via running the RStan example/test model:

I got the following error:
