error in installing Seurat V. 4

Question

[roberts]

Hello, I have been trying to download Seurat 4.0 with the command they gave -- remotes::install_github("satijalab/seurat", ref = "release/4.0.0") But I keep getting a list of packages to update. I have tried all the 36 options but the end result is always that installation failed because unable to remove prior installation of 'cowplot'. Did anyone else have this issue/what did you do to be able to download the new version of Seurat? Thanks

Try to remove cowplot by either remove.packages(cowplot) or try to delete the folder of the package at its actual location on disk, then retry installing Seurat. In Linux pacakges are usually at:

"/Library/Frameworks/R.framework/Resources/library"

edit: or more generic by typing .libPaths() into the R console as suggested below.

If that does not help please open an issue at the Seurat Github repo.

You can find out where your packages are stored via .libPaths()
