### Steps to reproduce

For the following code:

```lua
use {
    'hrsh7th/nvim-cmp',
    config = function()
        require 'plugins.nvim-cmp'
    end,
    requires = {
        {
            'hrsh7th/cmp-nvim-lsp',
            requires = {
                'williamboman/nvim-lsp-installer',
                config = function()
                    require('nvim-lsp-installer').setup()
                end,
                requires = 'nvim-lspconfig',
            },
        },
        {
            'saadparwaiz1/cmp_luasnip',
            requires = 'L3MON4D3/LuaSnip',
        },
        'hrsh7th/cmp-buffer',
        'hrsh7th/cmp-path',
        'hrsh7th/cmp-cmdline',
    }
}

packer couldn't find 'nvim-lspconfig'.

The issue here is with the requires for cmp-nvim-lsp. The issue is that you are only passing one table. requires can take either a string or a table. A string is passed for one require and a table for multiple requires. Since you are passing a table requires thinks there is a list of requirements. There is only one that is more complex then just a string.

To resolve this just add an extra table to the requires.

    use {
      'hrsh7th/nvim-cmp',
      config = function()
        print 'nvim-cmp config'
      end,
      requires = {
        {
          'hrsh7th/cmp-nvim-lsp',
          requires = {
            {
              'williamboman/nvim-lsp-installer',
              config = function()
                print 'nvim-lsp-installer config'
              end,
              requires = 'nvim-lspconfig',
            },
          },
        },
        {
          'saadparwaiz1/cmp_luasnip',
          requires = 'L3MON4D3/LuaSnip',
        },
        'hrsh7th/cmp-buffer',
        'hrsh7th/cmp-path',
        'hrsh7th/cmp-cmdline',
      },
    }

Yeah, it's my fault... solved! thx...
