Neovim: E518: Unknown option: cursorlineopt=number

[ckp95]

Trying Neovim with this minimal init.vim

let mapleader = "\<Space>"

:filetype plugin on
:syntax on
:filetype indent on

call plug#begin('~/.config/nvim/plugged')

Plug 'sheerun/vimrc'
Plug 'sheerun/vim-polyglot'
Plug 'phanviet/vim-monokai-pro'

call plug#end()

colorscheme monokai_pro

After installing and reloading I get the error:

Error detected while processing /home/cameron/.config/nvim/plugged/vimrc/plugin/vimrc.vim:
line  179:
E518: Unknown option: cursorlineopt=number

I commented out the offending line in the plugged/vimrc/plugin/vimrc.vim file and the error went away.
