Can't work with rocks.nvim

[mimikun]

When I install the plugin and run it with :Fall file, I get an error.

I am a Neovim user. I use rocks.nvim as my plugin manager. Not only vim-fall, but plugins made with denops are not compatible with rocks.nvim.(maybe) (I plan to ask rocks.nvim about this later)

The same denops plugin skkeleton worked fine, but vim-fall didn't work properly. Could you please tell me what the problem is?

Error

:Fall file
[denops] [fall] Failed to load source extension 'file': No source extension 'file' is registered

Repro

cd ~/.config
git clone https://github.com/mimikun/nvim-vim-fall-minimal-repro.git
export NVIM_APPNAME="nvim-vim-fall-minimal-repro"
nvim -u NORC -c "source https://raw.githubusercontent.com/nvim-neorocks/rocks.nvim/master/installer.lua"
# NOTE: install phase question 
# Set up luarocks (recommended) ?: false
# NEED set false, because an error occurs.

after neovim launch

Run :Rocks sync, and Fall file

Does vim-fall exists in runtimepath? Currently, vim-fall tried to find extensions from runtimepath (this behavior is planned to be changed though.)
