Cant install nolanlab/Rclusterpp

[jd11572]

I recently updated R to the 3.6.1 version. I am interested in installing the nolanlab/Rclusterpp package in RStudio, but I receive the following error: " Could not find tools necessary to compile a package". . I tried installing the packages on their own (eg. nolanlab and Rclusterpp), but I receive the error message saying that the packages are not available (for R version 3.6.1). Any help would be greatly appreciated
