I’m running a code in stan and for some time now it has stopped running, I really don’t know what to do. I installed new versions of the library and the program and I’m still getting this problem.

```
> # fit model
> check_cmdstan_toolchain(fix=T)
The C++ toolchain required for CmdStan is setup properly!
> set_cmdstan_path("/Users/marioquijada/.cmdstan/cmdstan-2.30.0")
CmdStan path set to: /Users/marioquijada/.cmdstan/cmdstan-2.30.0
> setwd("/Users/marioquijada/R")
> mod <- cmdstan_model("timeVarying.stan", pedantic=T)
Compiling Stan program...
