After installation, :ZettelOpen doesn't work

[interfect]

I installed the plugin and fzf, and set g:nv_search_paths in my ~/.vimrc. Now, when I try to :ZettelOpen (which is the only command the README describes the plugin as providing), it throws up a bunch of errors instead of starting an interactive search of my empty Zettel directory.

I'm using the GVim that ships with Ubuntu 20.04, which is Vim 8.1.

Did I do the installation wrong? Is my Vim insufficient in some way? Is there some other command that the plugin provides as an entry point besides :ZettelOpen?

It looks like, to run properly on Vim 8.1, #84 needs to be merged.

@interfect Did you figure out how to use the fork of #84 to work around it? I've been facing the same issue. I was wondering if using binary files directly and setting the &rtp to point to that location to make it work. This might be relevant, though I'm still stuck. I'm working on Windows 10 though.

[interfect]

@achieveordie No, I haven't yet. I think if you put that on the default branch of any repo you can use that repo with the plugin manager, but Vundle still has VundleVim/Vundle.vim#35 not really fixed and can't be told to use a non-default branch.

[interfect]

I put it up in interfect/vim-zettel, but it still doesn't work; something about the fzf_popd function is broken still in 8.1.

I am also getting this issue with vim 8.1.

@interfect do you still experience thiss issue?
