Question

I'm in the configuration neovim I added the configuration file in C:\Users\wupan\AppData\Local\nvim\init.lua

require("lua.plugins")

and C:\Users\wupan\AppData\Local\nvim\lua\plugins.lua

return require('packer').startup(function()
use "wbthomason/packer.nvim"
end)

After the start-up neovim

Error detected while processing C:\Users\wupan\AppData\Local\nvim\init.lua:

May I ask why

I tried to install Lua test the require

scoop install lua

C:\Users\wupan\code\lua\test.lua

require("hello")

C:\Users\wupan\code\lua\hello.lua

print("hello world")

There are also problems

Problem analysis

Let's use the following example which you gave us:

C:\Users\wupan\AppData\Local\nvim\init.lua

require("lua.plugins")

C:\Users\wupan\AppData\Local\nvim\lua\plugins.lua

return require('packer').startup(function()
    use "wbthomason/packer.nvim"
end)

And now let's take a look into your error message:

    no file 'C:\Users\wupan\scoop\apps\neovim\current\bin\lua\lua\plugins.lua'

The important part is the bin\lua\lua thing here. It's because your require("lua.plugins") starts to look up a directory in one of your runtime path (see :h rtp for more information).

Solution

You just need to fix your content in C:\Users\wupan\AppData\Local\nvim\init.lua to:

require("plugins")

because then neovim will look up a directory which is named plugins in C:\Users\wupan\scoop\apps\neovim\current\bin\lua for example, since its in your runtime path.

Little note

You can change your content from C:\Users\wupan\AppData\Local\nvim\lua\plugins.lua to:

require('packer').startup(function()
    use "wbthomason/packer.nvim"
end)

or how I did it:

local packer = require('packer')

packer.startup(function(use)
    use 'wbthomason/packer.nvim'
end)

That makes it a little bit more readable in my opinion :)
