Neovim - vim-grepper 没有显示结果

Question

I use Vim daily and use vim-grepper ( https://github.com/mhinz/vim-grepper ) as my grep plugin.

But since last week, it doesn't work anymore and every request I do result in... nothing found.

I tried to PlugUpdate , uninstall then reinstall it again, tried to do a basic grep :grep 'my_pattern' /my_project , I even tried installing an other grepper plugin but no result so far...

I have no idea what could have cause since I rarely update my vim config file and I'm not good enought yet at touching vim stuff, the only recent thing I did was source % on my config file but on I didn't edited lines concerning my grepper config.

Here is my config file in case it can help (located at ~/.config/nvim/init.vim) :

if (has("nvim"))
  "For Neovim 0.1.3 and 0.1.4 < https://github.com/neovim/neovim/pull/2198 >
