Error in `package_file()`: pllittle/smarter is not a directory.

Hi, I receive this error when downloading the UNMASC package,
for this particular step:

for(pack in req_packs){
	
	chk_pack = tryCatch(find.package(pack),
		error = function(ee){NULL})
	
	if( !is.null(chk_pack) ){
		library(pack,character.only = TRUE)
		next
	}
	
	if( pack %in% cran_packs ){
		install.packages(pack,dependencies = TRUE)
	} else if( pack %in% bioc_packs ){
		BiocManager::install(pkg = pack,dependencies = TRUE)
	} else if( pack %in% github_packs ){
		devtools::install(sprintf("pllittle/%s",pack),
			dependencies = TRUE)
	}
	
}

thank you!

I think devtools::install_github must be used instead of devtools::install but I haven't tried so don't know if this is the correct answer.
My way of avoiding this error is replacing

	} else if( pack %in% github_packs ){
		devtools::install(sprintf("pllittle/%s",pack),
			dependencies = TRUE)**
	}

with

	} else if( pack %in% github_packs ){
                  remotes::install_github(sprintf("pllittle/%s",pack)
	}

Please see here.
You should have remotes package installed in advance.
