Stan with Mojave MacOS

#1

Hi everyone,

I recently updated my MacOS software to Mojave and since I have not been able to use Stan with R. When I try loading the ‘rstan’ package, I get the following error:

library(rstan)
Loading required package: StanHeaders
Error in value[3L] :
Package ‘StanHeaders’ version 2.17.2 cannot be unloaded:
Error in unloadNamespace(package) : namespace ‘StanHeaders’ is imported by ‘rstan’ so cannot be unloaded

I have tried to look at re-installing RStan, but when I execute

pkgbuild::has_build_tools(debug = TRUE)

I return FALSE, so I think it might be something wrong with my C++ toolchain. I followed some pages to https://github.com/stan-dev/rstan/wiki/Installing-RStan-from-source-on-a-Mac#prerequisite--c-toolchain-and-configuration, which states that the macOS R toolchain installer isn’t ready for Mojave yet. Does this mean I’m going to just have to wait til the installer is out?

I’m not really sure what this necessarily means, so any help would be much appreciated!

Thank you
Ryan

Hello!

A friend of mine solved this issue using the console with the following lines

xcode-select --install

cd /Library/Developer/CommandLineTools/Packages

open .

Then, you should be able to install toolchain.

We need to see more of the error message, particularly the part with the string error:.
