Package not able to run stanc

[s-mishra]

I am trying to run the vignette example and it returns the error

  ! System command 'stanc' failed```

I have checked that I have cmdstan/cmstanr installed correctly. Have called them separately and it all works. 

Any help is appreciated.

I can't replicate the problem. Which command in the vignette is causing it?
