I am trying to install the package devtools on my mac. I downloaded Xcode but I am still unable to install devtools. I got this messages:
- installing source package ‘zip’ ...
** package ‘zip’ successfully unpacked and MD5 sums checked

Warning in install.packages :

And the message continues like that...
I tried on my windows computer...
I installed Rtools40 as explained on this website: Using Rtools40 on Windows
I was even able to install the package as they ask to check : ```
install.packages("jsonlite", type = "source")
However, when I am running the check command to see if I have problems in my package, I obtained an error message which say:
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:
https://cran.rstudio.com/bin/windows/Rtools/
Do you have any idea?
