Help with migration from lsp-installer to mason.nvim

[kozikowskik]

Hi,
Today I tried to switch from lsp-installer to mason.nvim and mason-lspconfig.nvim but I'm facing problems or I'm doing something wrong in the configuration and I don't see what. For testing I prepared a fresh neovim installation with packer and minimum configuration required to run ray-x/navigator.lua, mason.nvim and mason-lspconfig.nvim.With :LspInstall I installed pyright.
As result, I want to have running pyright as my lsp-serve for python files but when I run :LspInfo on some dummy python script I'm getting information that any of lsp clients is attached to buffer.

Neovim version:

My nvim configuration file looks like that:

return require('packer').startup(function(use)
  -- Packer can manage itself
  use 'wbthomason/packer.nvim'

  use("williamboman/mason.nvim")
  use({
          "williamboman/mason-lspconfig.nvim",
          config = function()
                  require("mason").setup()
                  require("mason-lspconfig").setup({})
          end,
  })
  use {"neovim/nvim-lspconfig"}
  use({
          "ray-x/navigator.lua",
          requires = {
                  { "ray-x/guihua.lua", run = "cd lua/fzy && make" },
                  { "neovim/nvim-lspconfig" },
                  { "nvim-treesitter/nvim-treesitter" },
          },
          config = function()
                  require("navigator").setup({
                          debug = true,
                          mason = true,
                  })
          end,
  })
end)

When I run :LspInstall inside the buffer I'm getting list of available servers with information that pyright is already installed:

Please select which server you want to install for filetype "python":
1: jedi_language_server
2: pylsp
3: pyright (installed)
4: sourcery
Type number and <Enter> or click with the mouse (q or empty cancels):

I create a feature request in mason: williamboman/mason-lspconfig.nvim#44

the reason is pylsp was install in virtual env path. It is not a binary lspconfig usually deal with.
You can setup pylsp by set navigator.setup{lsp={ pylsp ={ cmd={'mason_install_path'} } ATM
