Packer.nvim installation problem - git-submodules without URL

[jonasrogert]

I have an issue where vim-coiled-snake cannot be installed using neovim nightly and Packer.nvim

Error when trying to update using packer:

✗ Failed to update kalekundert/vim-coiled-snake
  Errors:
    Already up to date.
    fatal: No url found for submodule path 'tests/issues/dummy_home_16/.vim/pack/dev/start/vim-gitgutter' in .gitmodules
    431d705

Same error when running git submodule update --init --recursive which is what packer is using.

% git submodule update --init --recursive
fatal: No url found for submodule path 'tests/issues/dummy_home_16/.vim/pack/dev/start/vim-gitgutter' in .gitmodules

Result is that it wont install.

I did a fast temporary fix for it by removing the vim-gitgutter directory. I can't actually find any submodule reference to the vim-gitgutter folder so im not sure really how this happend. It might be only my setup...

It will probably break tests, not sure how tests and so works in vim.

I confirm, plugin cannot be installed or even updated using Packer.nvim.

Temporary solution without modifying the source code is to clone plugin manually into your packer/opt dir:
and add lock=true option into your nvim config, to not try updating it during sync/update of all other packages.

This is what i used (+lazy-load it by file type) (path is just example):

git clone https://github.com/kalekundert/vim-coiled-snake.git ~/.local/share/nvim/site/pack/packer/opt/

local use = require('packer').use
-- FIXME: locked -> to not try updating it. Till fix arrive (kalekundert/vim-coiled-snake/issues/33)
use {'kalekundert/vim-coiled-snake', lock=true, ft='python'} -- python code folding

:PackerSync after all
