Error when trying to set Kanagawa colorscheme

Question

I installed Kanagawa plugin using vim-plug.

When I tried to change the colorscheme with:

:colorscheme kanagawa

I got the following error :

>- Error detected while processing /home/mmip/.local/share/nvim/site/plugged/kanagawa.nvim/colors/kanagawa.vim:

I have been trying to figure it out looking to this post (very similar question), but eventually I didn't manage to solve the problem.

Here is how I installed the plugin using vim-plug : in my init.vim file I added:

Plug 'rebelot/kanagawa.nvim'

Inside the

call plug#begin('~/.local/share/nvim/site/plugged
" ...
call plug#end()

Then I called:

:PlugInstall.

My version of nvim is v0.6.1.

Answer 1

In my test the kanagawa colorscheme requiers Neovim 8.0.

It seems to me that Neovim 6.1 doesn't yet support colorscheme developed in Lua.

Apparently kanagawa colorscheme requiers some standard highlighting groups that are not yet standard in Neovim 7.0.

I suggest to migrate to Neovim 8.0 or above.
