error in installing causalTree - solved

[GeraldoASF]

I am trying to install causalTree and I am receiving the following messages.

install_github("susanathey/causalTree")
Downloading GitHub repo susanathey/causalTree@master
Error: Could not find tools necessary to compile a package

install_github("susanathey/causalTree", dependencies =T)
Downloading GitHub repo susanathey/causalTree@master
Error: Could not find tools necessary to compile a package

I have been working with RStudio 3.6.0 and Windows 10 and I have already installed 'devtools' and 'make'. Do you have a hint on how to overcome that problem?

Hi @GeraldoASF, thanks for the issue. For references for future users, this "necessary tools" error shows up on Windows because:

• The system did not have the correct version of rtools installed
• Issues with the development version of devtools (in my experience, Windows users are better off sticking with the CRAN release)
