null-ls.nvim/lua/null-ls/init.lua:32: attempt to call field 'nvim_create_user_command' (a nil value)

[adamu]

Hello.

I'm attempting to set up null-ls with credo.

I've installed plenary.nvim and null-ls.nvim with vim-plug:

Plug 'nvim-lua/plenary.nvim' " required for null-ls
Plug 'jose-elias-alvarez/null-ls.nvim'

And put this in my .vimrc:

lua << EOF
local null_ls = require("null-ls")

null_ls.setup({
    sources = {
        null_ls.builtins.diagnostics.credo,
    },
})
EOF

However, after adding this, I get the following error:

Error detected while processing /Users/adam/.vimrc:
line   31:
E5108: Error executing lua /Users/adam/.vim/plugged/null-ls.nvim/lua/null-ls/init.lua:32: attempt to call field 'nvim_crea
te_user_command' (a nil value)
stack traceback:
        /Users/adam/.vim/plugged/null-ls.nvim/lua/null-ls/init.lua:32: in function 'setup'
        [string ":lua"]:3: in main chunk

Does anyone have any ideas? I'm not familiar with using Lua with nvim yet.

I updated neovim from 0.6 to 0.8 and I don't get the error any more.
