RStan (and brms) suddenly stopped working for me while I was trying to solve some bookdown package update problems. I followed the instructions here: [image] RStan Getting Started RStan, the R interface to Stan. Contribute to stan-dev/rstan development by creating an account on GitHub. …

another R 4.0 matter; also solved in one of the threads here (sorry, don’t know by heart which one)

The *conda installations are finicky with Stan and may have their own configuration files. Basically with R 4.0, you want to only use the compiler / libraries / headers / etc. that come with Xcode. Maybe someone else who has RStan installed via miniconda knows how to do that?

BTW, I didn’t install RStan using miniconda.

[image] vasishth: /Users/shravanvasishth/miniconda3/bin/…/include/c++/v1/stdlib.h:94:15: fatal error: ‘stdlib.h’ file not found I am not sure why, but it is looking for non-existent files under Users/shravanvasishth/miniconda3/.
