@wsdjeg On May 9 2020, coc.nvim project has deleted the coc.nvim/install.sh file. It breaks following code:
https://github.com/SpaceVim/SpaceVim/blob/b90c7fb57a516bf473b7f1af5d32f832914ca9dc/autoload/SpaceVim/layers/autocomplete.vim#L70
Yes I had the same problem on macos as well. The installation needs to be changed according to https://github.com/neoclide/coc.nvim/wiki/Install-coc.nvim#using-deinvim
Same on archlinux

Guys, there is a temporary solution to fix the issue.
cd ~/.cache/vimfiles/repos/github.com/neoclide/coc.nvim/
git checkout .
git pull
git checkout release

This doest solve anything for me.

@dev-martin Maybe, you need to clone coc.nvim again to the directory.
cd ~/.cache/vimfiles/repos/github.com/neoclide/
rm -fr coc.nvim
git clone https://github.com/neoclide/coc.nvim
cd coc.nvim
git checkout release
