In this discussion you can ask questions and report problems you encountered while setting up MAgPIE using the how to install section of the readme.

Known problems

Rtools not found

If you get an error like Error : Could not find tools necessary to compile a package on Windows your Rtools setup is not working yet. Make sure you installed the RTools version matching your R version. Make sure the environment variable RTOOLS43_HOME (for R/Rtools 4.3; replace "43" with your R/Rtools version if needed) is set to the path to the Rtools directory.

R package system requirements missing

When installing R packages from source (usually only on Linux/Mac) sometimes system libraries are missing. You can look up system requirements and how they are called for your system at https://sysreqs.r-hub.io/pkg/<package-name>, replacing <package-name> with the package that fails to install. Then you usually just need to install the missing packages via your package manager, e.g. brew on Mac, and apt on Ubuntu.

For example for the ragg package: https://sysreqs.r-hub.io/pkg/ragg
So on Mac you'd need to run brew install libpng libtiff, on Ubuntu it would be sudo apt install libpng-dev libtiff-dev.
