nvim-lsp-installer middleware module not found

[calbch]

Hey guys, when calling

installer.setup {
  ui = {
    icons = {
      server_installed = "✓",
      server_pending = "➜",
      server_uninstalled = "✗"
    }
  }
}

...nvim-lsp-installer/lua/nvim-lsp-installer/middleware.lua:1: module 'lspconfig.util' not found: is thrown.

If I require('nvimn-lsp-installer/middleware') in an otherwise empty lua file
the same error is thrown: ...nvim-lsp-installer/lua/nvim-lsp-installer/middleware.lua:1: module 'lspconfig.util' not found

Since I just started getting into nvim I am not entirely sure if this is a bug or if it's a brainfart on my end.

The full repository can be found here:

Thank you in advance and excuse me, if this is something super obvious!

Figured it out! I needed to use

use {
    "williamboman/nvim-lsp-installer",
    "neovim/nvim-lspconfig",
  }

instead of

 use({
    "neovim/nvim-lspconfig",
    event = "BufReadPre",
    requires = {
      { "williamboman/nvim-lsp-installer" }
    },
  })

in my packer config. The second case installed the package in /opt instead of /start.
This leads to local util = require "lspconfig.util" in middleware not being resolved correctly.
