Installing cmdstan for cmdstanr

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!

If possible, add also code to simulate data or attach a (subset of) the dataset you work with.

thank you so much on advance!

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