warning in install.packages

I want to use install_zip_gh to install "YuLab-SMU/ggtree",but it has some trouble:

library(ggtree) Error in library(ggtree) : there is no package called ‘ggtree’

how could I solve this problem? Should I update my R to R-4.0?

I only test the package on Linux. Don't know whether the PR solve your problem or not.
