Spawning the language server with cmd: lua-language-server failed. The language server is not either installed, missing the path or not executable.

I installed sumneko_lua by nvim-lsp-installer. But it doesn't work properly. The configuration of nvim-lsp-installer is default. This problem happened in Windows and EndeavourOS. Do I need to add path of language server manually?

You don't have to manage paths manually with nvim-lsp-installer. When setting up servers via nvim-lsp-installer, the necessary PATH will be managed for you. How are you setting up servers? See https://github.com/williamboman/nvim-lsp-installer#setup for a minimum setup example

None of my installs work too, and everytime I go into a file (python, lua, etc.) I have a server installed for, I get the same error.

I required my nvim-lsp-installer config before the lspconfig config and it worked

Today I've had the same issue as you. Just place its setup config before any language server, and it worked.

That solved it for me as well @williamhCode thank you.

Use Mason instead of nvim-lsp-installer and make sure you use PATH = "prepend" -- instead of "skip" in your config as illustrated below:

require("mason").setup({
    PATH = "prepend", -- "skip" seems to cause the spawning error
})
