Volar tries to look for tsserver library in project directory instead of Mason's installation directory for Volar

[whollingsworth]

Problem description

I'm running into the following error when opening a Vue file. It looks like Neovim is looking for tsserverlibrary.js in my project's node_modules folder instead of Mason's installation directory for the language server, which does have it.

Error executing vim.schedule lua callback: ...neovim/HEAD-12fe197_1/share/nvim/runtime/lua/vim/lsp.lua:1284: RPC[Error] code_name = InternalError, message = "
Request initialize failed with message: Cannot find module '/Users/whollingsworth/<project-directory>/node_modules/typescript/lib/tsserverlibrary.js'

        vim/_editor.lua: in function <vim/_editor.lua:0>

Why do you think this is an issue with mason-lspconfig.nvim?

williamboman/mason.nvim#108 mentioned a similar issue was fixed in this project.

Neovim version (>= 0.7)

$ nvim --version
NVIM v0.8.0-dev-2465-g12fe197cf
Build type: Release
LuaJIT 2.1.0-beta3

Operating system/version

macOS Darwin Kernel Version 21.6.0 / Monterey 12.5.1

I've manually reviewed the Nvim LPS client log (:LspLog) to find potential errors

• Yes

I've recently downloaded the latest plugin version of mason.nvim, mason-lspconfig.nvim, and nvim-lspconfig

• Yes

Affected language servers

Volar

Steps to reproduce

1. Create a new Vue project (vue create hello)
2. Open src/App.vue

Actual behavior

The server does not start because Neovim looks for a required library in the projects node_modules directory instead of the server's

Expected behavior

The server starts

Hello! I am unable to reproduce this. Do you have a sample repo perhaps? I tried vue create but were unable to reproduce (it also seems like that CLI is deprecated)

[whollingsworth]

Oh, interesting. I was following a tutorial on Vue Mastery and wasn't aware that Vue CLI was in "maintenance mode". If I create a project with vuejs/create-vue instead, the server seems to start fine. I think it's fair to close this if Vue CLI is deprecated. Thank you!

I've faced this error in a brand new Nuxt.js project, however it is weird that this is not happening in a regular Vue project.

The only way I could make it work was explicitly specifying the tsdk in the Volar config, example:

require'lspconfig'.volar.setup{
  init_options = {
    vue = { hybridMode = false },
    typescript = {
      tsdk = vim.fn.stdpath'data' .. '/mason/packages/typescript-language-server/node_modules/typescript/lib'
    }
  },
}

This other issue seems to be similar #74.
