How to reproduce the problem from neovim startup

After installing with :LspInstall I get:

Error executing vim.schedule lua callback: ...r/neovim/HEAD-60c581b/share/nvim/runtime/lua/vim/lsp.lua:460: RPC[Error] code_name = InternalError, message = "Request initialize failed with message: Couldn't find 'tsserver' e
xecutable or 'tsserver.js' module"

Uninstalled and then tried to install from npm and same issue.

gopls and vim-language-server both work perfectly.

Can you start tsserver manually?

[nhooyr]

~/src/nhooyr/websocket:dev*
$ ~/.cache/nvim/nvim_lsp/tsserver/node_modules/.bin/typescript-language-server 
Connection type required (stdio, node-ipc, socket). Refer to --help for more details.

Can run the binary at least.

How do I start it up properly?

[lithammer]

You didn't actually start it though since it failed because of missing arguments. As the error message says, you need to start it with a connection type, e.g. stdio, node-ipc, socket.

Try this instead:

-~/.cache/nvim/nvim_lsp/tsserver/node_modules/.bin/typescript-language-server
+~/.cache/nvim/nvim_lsp/tsserver/node_modules/.bin/typescript-language-server stdio

[nhooyr]

So passing --stdio and it blocks so it seems like it works but passing --node-ipc or --socket 9090 and it just exits without any error/log.

Anyway, I meant to use the node language server and it doesn't seem tsserver not working is related to nvim-lsp.

[nhooyr]

Oh wait hold on there is no node ls server. tsserver is the main one my bad.

I was looking at https://github.com/microsoft/vscode-languageserver-node but that seems to just be a library.

[nhooyr]

omfg I just had to install typescript globally

npm install -g typescript

Not sure why the package doesn't depend on typescript. interesting.

[nhooyr]

I'd say that's a bug in nvim-lsp actually, we should install tsserver on top of typescript-language-server if we have to.

[lithammer]

I think the assumption is that you should install typescript locally in your project (i.e. add it to package.json).

[nhooyr]

I think the assumption is that you should install typescript locally in your project (i.e. add it to package.json).

Yea I should have ran yarn to install deps first but I got blocked on figuring this out lol. I think an error message would be appropriate explaining that.

[dsummersl]

Ran into this issue and @nhooyr 's typescript install did it for me too - would be nice if the docs reflected this need!

[mawkler]

It would be awesome if Neovim printed out an error saying that the LSP is missing a typescript install

[alexaandru]

I for one still can't get JavaScript LSP working: nvim -u test.vim test.js shows no diagnosis error, where

test.vim is:

packadd nvim-lspconfig
lua require'nvim_lsp'.tsserver.setup{}

and test.js is:

var foo = 1
vax bar = 2

lua print(vim.inspect(vim.lsp.buf_get_clients())) returns {}. :checkhealth is happy, I did install typescript globally, tsserver config looks good:

{                                                                                                                                                                                                           
  bin_dir = "/home/alex/.cache/nvim/nvim_lsp/tsserver/node_modules/.bin",
  binaries = {
    ["typescript-language-server"] = "/home/alex/.cache/nvim/nvim_lsp/tsserver/node_modules/.bin/typescript-language-server"
  },
  install_dir = "/home/alex/.cache/nvim/nvim_lsp/tsserver",
  is_installed = true
}

and I can run typescript-language-server just fine. I just don't get any of the LSP goodness at all...

I use the latest master for nvim-lspconfig and nvim version is v0.5.0-715-gc5ceefca7.

[miiila]

@alexaandru What OS do you have? I just struggled very hard on new Linux machine, because I (wrongly) ran all the npm install -g commands with sudo (can happen on other platforms as well, I guess).

Should it be the case, make sure you follow https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally.

[alexaandru]

Thank you @miiila , my bad & sorry for the noise everyone: my test case was flawed - forgot about the trigger, which must be one of "package.json", "tsconfig.json", ".git" - without that, the LSP will not kick in :) - https://github.com/neovim/nvim-lspconfig#tsserver

It works now, I get errors, hints & all the LSP goodness :)

[mjlbach]

Is this still an issue?

[beauwilliams]

FYI You don't need a trigger if you use this config root_dir = vim.loop.cwd

Here is my full code. You can simply run nvim test.ts in any folder and you get completion. No need to be in git etc..

lsp.tsserver.setup {on_attach = custom_attach, root_dir = vim.loop.cwd }

[mjlbach]

I would recommend not overriding the default, but adding a fallback root_dir = util.root_pattern("package.json", "tsconfig.json", ".git") or vim.loop.cwd();

See: https://github.com/neovim/nvim-lspconfig/blob/42a13e5ad99b688bc7376fa4d236e924985d04cc/lua/lspconfig/intelephense.lua#L18-L22 https://github.com/neovim/nvim-lspconfig/blob/42a13e5ad99b688bc7376fa4d236e924985d04cc/lua/lspconfig/clangd.lua#L21-L23

[beauwilliams]

Thanks, I see that my approach was a bit rough. I have tried refactoring my lsp_config.lua entry for tscript like so

Now I can't seem to get any completions working when running nvim test.ts

local util = require 'lspconfig/util'

lsp.tsserver.setup {on_attach = custom_attach, root_dir = util.root_pattern("package.json", "tsconfig.json", ".git") or vim.loop.cwd(); }

/Thank you haha, i had the same issue. Killing it :)))

[sergii4]

My nvim lsp can't run tsserver, :LspInfo shows:

Config: tsserver
      cmd is executable: False. Please check your path and ensure the server is installed

it can see executable if I set it up directly:

nvim_lsp.tsserver.setup{
    cmd = {'tsserver'}
}

then I see:

LSP[tsserver]: Error INVALID_SERVER_MESSAGE: {
  command = "unknown",
  message = "Error processing request. Unexpected token C in JSON at position 0\nSyntaxError: Unexpected token C in JSON at position 0\n    a

[sergii4]

I have some progress with https://github.com/neovim/nvim-lspconfig/blob/master/lua/lspconfig/tsserver.lua#L25

npm install -g typescript typescript-language-server

now:

 cmd is executable: True

[lithammer]

@sergii4 the tsserver binary doesn't actually implement LSP (yet, see https://github.com/microsoft/TypeScript/issues/39459). Which is why you need to install something like typescript-language-server that acts as an adapter on top of tsserver and exposes an LSP interface:

cmd = {'typescript-language-server', '--stdio'}

[sergii4]

thanks, @lithammer. I just expected this to be somewhere in nvim lspconfig docs.

[mjlbach]

Fwiw you don't need to manually specify command, as you're overwriting the default (correct) value

[sergii4]

@mjlbach the case is that I couldn't run with default settings even after I used this:

https://github.com/neovim/nvim-lspconfig/wiki/Installing-language-servers-automatically (https://github.com/alexaandru/nvim-lspupdate particulary).

So I started experimenting and ened up with: https://github.com/neovim/nvim-lspconfig/blob/master/lua/lspconfig/tsserver.lua#L25

Probably manual needs an update

[mjlbach]

What do you mean manual needs an update? Which manual? Which update? That command is in our docs ^

[sergii4]

what i was looking of is how to setup nvim lspconfig with tsserver. I haven't found it. I you have it, could you please share it with me?

[lithammer]

what i was looking of is how to setup nvim lspconfig with tsserver. I haven't found it. I you have it, could you please share it with me?

As I said, it's not possible since tsserver isn't a language server. Just install typescript-language-server and it will use tsserver under the hood.

[sergii4]

Добре?

what is the point of your message? you just repeated the things I listed before. what i was needed I found here. It wasn't listed in projected wiki. that was my point.

I am dumb, sorry

lsp.tsserver.setup {on_attach = custom_attach, root_dir = vim.loop.cwd }

This worked. Thank you!!

[ehpc]

I use this settings to find _rootdir with fallback to cwd.

require('lspconfig')['tsserver'].setup{
  on_attach = on_attach,
  root_dir = function (pattern)
    local cwd  = vim.loop.cwd();
    local root = util.root_pattern("package.json", "tsconfig.json", ".git")(pattern);
    return root or cwd;
  end;
}

[nyngwang]

The problem seems to have been fixed, so one can just use the default settings. In my case, I have been using autostart = true without customizing root_dir and everything is working for months.

[carlosgrillet]

For me worked npm install -g typescript typescript-language-server and then in my nvim config require('lspconfig').tsserver.setup{}

[coffeebe4code]

what is a minimum working non lspconfig setup?
