I have tried all the available servers the config has: pyls, pylsp, pyright, but none of them work. I have followed the debugging steps on the main page and have noted the default configurations in the CONFIG.md file. I originally opened an issue a while back and since then I have still not figured out a solution (getting desperate lol; see original issue here - Am I the only one where both `pyls` and `pylsp` are not attaching? · Issue #893 · neovim/nvim-lspconfig · GitHub).
For example, for pylsp I have followed all the steps:
pipx install 'python-lsp-server[all]'
mkdir test_py
git init
python3 -m venv venv
source venv/bin/activate
# I even tried installing pylsp in my virtualenv
touch requirements.txt # with some random stuff
touch main.py
nvim main.py
When I follow these steps and open main.py, I expect the language server to attach, but it doesn’t. When I run :LspInfo it recognizes that I have the server installed, but specifies that there are 0 clients attached.
Granted: I can start it myself by running something like :LspStart pylsp, but this is not ideal (maybe I’m lazy for sure) because I would have to re-run this for every file I open.
Really appreciate any help I can get with this, I have been struggling for months lol. I have a lua file where all my lsp-related things are initialized, here is a snippet of what happens in there:
local nvim_lsp = require'lspconfig'
local custom_attach = function(client)
print("LSP started.");
-- require'completion'.on_attach(client)
-- require('folding').on_attach()
-- require'diagnostic'.on_attach(client)
require'lsp_signature'.on_attach({
bind = true,
handler_opts = {
border = "single"
},
});
