Plugin Not Install with Vim-Plug

[pestala]

I am trying to get neuron working with neovim 0.7.0 using vim-plug 0.10.0. I've added the four plugins described in the setup for neuron to my init.vim file and done PlugInstall. All of my other plugins install as expected, but neuron, popup, plenary and telescope do not. Neovim doesn't throw any errors. I've got the neuron binary installed at /usr/bin/neuron.

I can't seem to find any help on google or the vim-plug repository on github related to this.

Any suggestions would be appreciated.

@pestala would be worth posting a link to your dotfiles/snippet of your plugins setup
