Mason installed LSP server don't seems to work

[fblackburn]

I just updated to the latest version of kickstart.nvim. I could not make my python lsp work until I uncommented the auto installation of pyright in the config. If I only installed it with Mason, it was not working when I opened a python file.

I tried installing the python parser manually with TSInstall python and it still didn't work.

It's probably a skill issue on my part, but I wonder what changed, in the past I could add a lsp to Mason and it was working without touching anything in the init.lua file.

Thanks!

TSInstall is provided by nvim-treesitter to install TreeSitter parsers, rather than LSP servers. If you want to install pyright manually using Mason, you can run:

MasonInstall pyright

or run:

Mason

(and then select pyright from the list of LSP servers)

I think I might have found a bug in the config.

Adding a server to the list_extend section:

vim.list_extend(ensure_installed, {
  -- You can add other tools here that you want Mason to install
})

Does not automatically configure/enable the servers:

-- Only `servers` is being looped over here
for name, server in pairs(servers) do
  vim.lsp.config(name, server)
  vim.lsp.enable(name)
end

To automatically install, and also automatically configure and enable the server, you must add it to the servers table:

local servers = {
  -- ... some other configs ...

  -- My configurations
  pyright = {},
}
