Getting errors if not in project directory

[matthewsia98]

In neovim, I am not getting any diagnostics if pylsp is running in single file mode. I do get diagnostics if opening a file under a git repository.

Seems like auto import doesn't work in non project files too

It seems to be failing when root directory is my home directory

[rstcruzo]

I get this error every time the directory I'm in is not a git repository. Can we reopen this?

[matthewsia98]

Try this

local lspconfig = require("lspconfig")
local util = require("lspconfig.util")
lspconfig.pylsp.setup({
      root_dir = function(fname)
          local root_files = {
              "pyproject.toml",
              "setup.py",
              "setup.cfg",
              "requirements.txt",
              "Pipfile",
          }
          return util.root_pattern(unpack(root_files))(fname)
              or util.find_git_ancestor(fname)
              or vim.fn.expand("%:p:h")
      end,
