I'm a longtime user of vim on Archlinux. I've been away from this system for a few months, so I can't be sure when this started (but I've made updates during this time, too).
Every time I open the app, I get an error about the spelling file.
$ vim
Warning: Cannot find word list "en.utf-8.spl" or "en.ascii.spl"
Warning: Cannot find word list "en.utf-8.spl" or "en.ascii.spl"

Press ENTER or type command to continue
$ vim --version

$ sudo pacman -Ss vim | grep installed

community/ranger 1.7.2-1 [installed]
I reinstalled the app, but the problem persists. The problem is for all users.
set spell
enabled but didn't downloaded the spell files. You can have a look at this blog post and this question. I think the solution is to download the spell files and put them in~/.vim/spell
. Note that usually vim offers to download the files automatically so I think the question I linked before might help you.
