Error installing package

Im trying to install the “Slippers” package from Github but I receive a long string of errors.

I’ve installed other packages from the same Github Repo without any problems but this package doesn’t seem to work.

I’ve tried using devtools and remotes to install the package but both return the same string of errors.

devtools::install_github(‘jtleek/slipper’)
