ERROR: compilation failed for package ‘nnet’

Question

I just updated R version to R 4.3.1. Together with the new R, I downloaded XQuartz-2.8.5.pkg and gfortran-12.2-universal.pkg.

In my project, the lockfile of my renv was generated with R 4.2.0. Initialising the project, it tells me:

- One or more packages recorded in the lockfile are not installed.
- Use `renv::status()` for more details.

I checked, and following the steps in ?renv::status() it says: "If you have multiple packages in an inconsistent state, we recommend renv::restore(), then renv::install(), then renv::snapshot(), but that also suggests you should be running status more frequently."

After running renv::restore() I successfully downloaded all missing packages, but when installing I get an error with package "nnet".

Error: Error installing package 'nnet':

Could anybody help me please?

I'm running a Mac with Ventura 13.5 and Apple M1 Pro

Thanks!

I tried searching on the internet but got no results...

Also, when I tried to instal the package outside the project (in a empty project) I could install it with no problems, so it might be something with the renv?
