What have you tried, and what errors (if any?) are you seeing?

other language servers work perfectly. (i am on windows)

[williamboman]

Since you're using lspconfig to set up servers, please make sure to use https://github.com/williamboman/mason-lspconfig.nvim

I just moved to mason and in order to make it work (everything is installed smoothly btw), I had to overwrite the cmd when trying to setup some of the lsp servers (like sumneko for example)

require('lspconfig')

local lsp_servers_path = vim.fn.stdpath('data') .. '/mason/packages'

local sumneko_path_bin = lsp_servers_path ..'/lua-language-server/extension/server/bin/'

and then (after defining the capabilities and all the stuff): cmd = { sumneko_path_bin .. 'lua-language-server.exe', '-E', sumneko_path_bin .. '/main.lua' };

maybe not the intended way, but it works.

i installed it and lazyloaded it

[williamboman]

Cool! Remember to use one of the issue templates in the future, clearly stating (i) what isn't working, (ii) what you've done to try to fix it yourself, (iii) why you believe it's an error with the plugin, and (iiii) any additional information (providing more information early on helps everyone involved)

[williamboman]

I found an issue in mason-lspconfig where executables were not always expanded properly on Windows, fixed in https://github.com/williamboman/mason-lspconfig.nvim/pull/7. Might be related to your issues

[benomine]

I'm so dumb ahah. It did not work at first because I called the lspconfig before calling mason and mason-lspconfig. Now everything is working great and the code needed to call each and every lsp is just simpler. Thanks

I'm still facing this issue but with mason-tool-installer. I'm not using mason-lspconfig yet because I need to auto-install other tools. The following shows up when I run :MasonLog before the log file opens, as well as when sumneko is needed:

I ended up adding Mason's binary path to $PATH in order for it to work out of the box. Not ideal, but it works.

[williamboman]

@re-kaptcha I checked your dotfiles and it seems like you’re relying on Neovims builtin runtime file loading. It will load your files in after/plugin/ in alphabetical order. You have to make sure Mason setup executes before you set up lspconfig servers.

@williamboman Thanks for the tip. I moved Mason's configuration into the lua directory, then called it in my lspconfig setup before initializing the servers. I thought letting making packer load Mason after lspconfig would work, but apparently not. Thanks again.
