Putting Rtools on the PATH

After installation is complete, you need to perform one more step to be able to compile R packages: you need to put the location of the Rtools make utilities (bash, make, etc) on the PATH. The easiest way to do so is create a text file .Renviron in your Documents folder which contains the following line:

PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"

You can do this with a text editor, or from R like so (note that in R code you need to escape backslashes):

writeLines('PATH="${RTOOLS40_HOME}\\\\usr\\\\bin;${PATH}"', con = "~/.Renviron")

Now restart R, and verify that make can be found, which should show the path to your Rtools installation.

Sys.which("make")
## "C:\\\\rtools40\\\\usr\\\\bin\\\\make.exe"

If this works, you can try to install an R package from source:

install.packages("jsonlite", type = "source")

If this succeeds, you’re good to go! See the links below to learn more about rtools40 and the Windows build infrastructure.
