init.lua nvim probleme

[Chandler B. (chandler)]

Hallo,
ich habe nVim auf Windows am laufen und habe probleme beim ausführen von 
init.lua

ich habe die Plugins

Plug 'giusgad/pets.nvim' | Plug 'MunifTanjim/nui.nvim' | Plug 'edluffy/hologram.nvim'

installiert

in meiner init.vim habe ich ganz am ende

lua require('init')

in dieser Datei steht

require'pets'.setup({
  row = 1, -- the row (height) to display the pet at (higher row means the pet is lower on the screen), must be 1<=row<=10
  col = 0, -- the column to display the pet at (set to high number to have it stay still on the right side)
  speed_multiplier = 1, -- you can make your pet move faster/slower. If slower the animation will have lower fps.
  default_pet = "dog", -- the pet to use for the PetNew command
  default_style = "brown", -- the style of the pet to use for the PetNew command
  random = true, -- whether to use a random pet for the PetNew command, overrides default_pet and default_style
  death_animation = true, -- animate the pet's death, set to false to feel less guilt -- currently no animations are available
  popup = { -- popup options, try changing these if you see a rectangle around the pets
    width = "30%", -- can be a string with percentage like "45%" or a number of columns like 45
    winblend = 100, -- winblend value - see :h 'winblend' - only used if avoid_statusline is false
    hl = { Normal = "Normal" }, -- hl is only set if avoid_statusline is true, you can put any hl group instead of "Normal"
    avoid_statusline = false, -- if winblend is 100 then the popup is invisible and covers the statusline, if that
    -- doesn't work for you then set this to true and the popup will use hl and will be spawned above the statusline (hopefully)
  }
})

Wenn ich jetzt jedoch meine init.vim neu lade, bekomme ich den Fehler

E5108: Error executing lua [string ":lua":1: loop or previous error loading module 'init'
stack traceback:
[C]: in function 'require'
[string] ":lua"}:1: in main chunk

Bzw. eigentlich ist das lua nicht wirklich das Problem.
Das Problem ist mehr, dass obwohl die Plugins installiert sind, die 
Befehle nicht bekannt sind.
Da stand auf https://github.com/giusgad/pets.nvim nur, dass anschließen

require("pets").setup({
  -- your options here
})

} aufgerufen werden muss.
