[SOLVED] Neovim, LSP, Mason - Python client not attaching to buffer

Neovim, LSP, Mason - Python client not attaching to buffer

In neovim NVIM v0.10.0-dev on Linux Mint. I wrote my whole config in 'lua' and I'm very happy so far. The only thing thats not working is lsp with python. I configured lsp and cmp and mason, mason-lspconfig. I works great with tex, java and html but the python client does not attach to the buffers. When opening a '.py' file I get the following error for pyright:

Client pyright quit with exit code 1 and signal 0. Check log for errors: ~/.local/state/nvim/lsp.log

The log gives me the following output:

 [ERROR][2023-08-11 16:49:35] .../vim/lsp/rpc.lua:675    "rpc"   "~/.local/share/nvim/mason/bin/pyright-langserver"   "stderr"    "internal/modules/cjs/loader.js:638\n    throw err;\      n    ^\n\nError: Cannot find module 'worker_threads'\n    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)\n    at Function.Module._load (internal/modules/cjs/loader      .js:562:25)\n    at Module.require (internal/modules/cjs/loader.js:692:17)\n    at require (internal/modules/cjs/helpers.js:25:18)\n    at Object.1267 (~/.local/share/nvim/mason/pac      kages/pyright/node_modules/pyright/dist/pyright-langserver.js:1:568)\n    at s (~/.local/share/nvim/mason/packages/pyright/node_modules/pyright/dist/pyright-langserver.js:1:744)\n          at Object.9560 (~/.local/share/nvim/mason/packages/pyright/node_modules/pyright/dist/pyright-internal.js:1:997879)\n    at s (~/.local/share/nvim/mason/packages/pyright      /node_modules/pyright/dist/pyright-langserver.js:1:744)\n    at Object.6334 (~/.local/share/nvim/mason/packages/pyright/node_modules/pyright/dist/pyright-internal.js:1:1327466)\n          at s (~/.local/share/nvim/mason/packages/pyright/node_modules/pyright/dist/pyright-langserver.js:1:744)\n"

and when I run :LspInfo in a '.py' file I get this:

 Language client log: ~/.local/state/nvim/lsp.log

Any Ideas on how to fix it? Can I force attachement?

I read somewhere that it might be an issue with 'node' not being up to date but I could not find any more details on how to update it.

If you need more info, I'm happy to provide it. Thanks

Solution

So the problem was with node or nodejs as it's called in the api. The official api just installed node 10.X. To remedy this - as @Zizizizz pointed out - it is possible to install the current version of node or on Linux Mint like so:

sudo apt-get install curl python-software-properties software-properties-common 

curl -sL https://deb.nodesource.com/setup_20.x | sudo bash - 

sudo apt-get update

sudo apt-get install nodejs
