Short summary of the problem
l want to run examples from rethinking package, but ulam funtion is problem when complie model. l have downloaded Rtool42 and cmdstan. but cmdstan is not by running install_cmdstan(). because the speed is unsuccessful
install_cmdstan()
The C++ toolchain required for CmdStan is setup properly!

Compiling Stan program…
Error in process_initialize(self, private, command, args, stdin, stdout, …:
! Native call to processx_exec failed
Caused by error in chain_call(c_processx_exec, command, c(command, args), pty, pty_options, …:

l do not know how to solve
If possible, add also code to simulate data or attach a (subset of) the dataset you work with.

You can try to run cmdstan in GoogleColab and see if there is any error
