I had to reinstall R and Rstudio on my laptop, and since then I am not able to install packages from source.
I checked the installation of rtools, and I think it should have worked.
> Sys.which("make")
make
"C:\\rtools40\\usr\\bin\\make.exe"
Whenever I try to install a package, it fails and I always get the same error:
> install.packages("jsonlite", type = "source")
Installing package into ‘C:/Users/Teresa/R/win-library/4.1’

This is my sessionInfo():

How can I solve this?
