Hi, I updated my R version to 4.3.1 and have had to reinstall cmdstanr.

I use the code
install.packages(“cmdstanr”, repos = c(“Repository for distributing (some) stan-dev R packages | r-packages”, getOption(“repos”)))

and the error messages:
Installing package into ‘C:/Users/X/AppData/Local/R/win-library/4.3’
(as ‘lib’ is unspecified)

Could you please take a look and help me with it?

Thank you!

I don’t know much about windows but this seems like the same error message from this issue:

Does anything discussed there help?

Yes, this is the same problem. After deleting the .cmdstan folder under /document, the package can be installed.

Thank you so much for your help!
