Ulam Error in CompileCode

Summary:

Please provide a short summary (no more than a sentence or two).
Having trouble running "ulam" function from rstan due to a compileCode error.

Description:

Describe the issue as clearly as possible.
Howdy everyone,

I am trying to run the ulam function, taken straight from the R code 9.16 of the second edition of statistical rethinking. I keep on getting the same error, over and over again, which I reported in the Current Output.

rstan is successfully installed, together with devtools and the rethinking package. Might be worth mentioning that the library is currently unspecified for me, and the packages have been installed in a different library directory than the one of the R 3.6.3 installation. This has not raised any problem while using other functions such as quap.

Any help is much appreciated!

Reproducible Steps:

Please report steps to reproduce the issue. If it's not possible to reproduce, please include a description of how you discovered the issue.
m9.1<-ulam(
alist(
log_gdp_std~dnorm(mu,sigma),
mu<- a[cid]+b[cid]*(rugged_std-0.215),
a[cid]~dnorm(1,0.1),
b[cid]dnorm(0,0.3),
sigmadexp(1)
), data=data_slim, chains=1)
If you have a reproducible example, please include it.

Current Output:

If applicable, any relevant output from RStan.
Error in compileCode(f, code, language = language, verbose = verbose) :

Expected Output:

If applicable, the output you expected from RStan.

RStan Version:

The version of RStan you are running (e.g., from packageVersion("rstan"))
2.19.3

R Version:

The version of R you are running (e.g., from R.version.string)
3.6.3

Operating System:

Your operating system (e.g., OS X 10.11.3)
Windows 10 Home 1903

Start with the reported ulam call and the RStan compileCode output on Windows 10 with R 3.6.3 and RStan 2.19.3. Investigate the reported C:/Program path error and library-directory details; done means identifying a reproducible cause and documenting a verified resolution.
