Installing rstan on RHEL 7.6

I’m unable to install rstan under RHEL 7.6 using the following command:

remotes::install_github("stan-dev/rstan", ref = "develop", subdir = "rstan/rstan", build_opts = "")

I receive the following error message:

remotes::install_github(“stan-dev/rstan”, ref = “develop”, subdir = “rstan/rstan”, build_opts = “”)

I can install rstan from CRAN, but then the 8 schools example doesn’t compile, providing an error message that it can’t find StanHeaders.
