can not find hex under debian12.5

[ziyouchutuwenwu]

i am not sure if this issue should be posted here or https://github.com/elixir-lsp/elixir-ls, here is the steps.

due to gfw, i download hex manually, then

mmc at deb-kvm in ~
$ mix archive.install ./hex-2.0.6.ez
Are you sure you want to install "./hex-2.0.6.ez"? [Yn]
* creating .mix/archives/hex-2.0.6

here is the snapshot of installed hex

when i create demo project

mix new demo

open with vscode, then check the elixirls output

Shall I install Hex? (if running non-interactively, use "mix local.hex --force")

it should be reported to https://github.com/elixir-lsp/elixir-ls

Something is wrong with your env or hex, not with elixirLS. There were similar reports already here and on elixir forums. Please use search

sorry for reopening this issue, i found need to run Code.append_path for debian, as i posted https://github.com/elixir-lsp/elixir-ls/issues/1092, i don't know how to add dir /home/mmc/.mix/archives/hex-2.0.6/hex-2.0.6/ebin/ to system beam path automaticlly.

here is my code for $HOME/.vscode/extensions/jakebecker.elixir-ls-0.21.1/elixir-ls-release/installer.exs

defp load_hex do
  if !Code.ensure_loaded?(Hex) do
    base_dir = System.user_home |> Path.join(".mix/archives")

    if base_dir |> File.exists? do
      sub_dirs = File.ls!(base_dir)
      if sub_dirs |> Enum.count() > 0 do
        hex_dirs = Enum.filter(sub_dirs, fn dir -> dir |> String.starts_with?("hex-") end)

        hex_dir = Enum.reduce(hex_dirs, fn dir, saved_dir ->
          start_pos = String.length("hex-")
          ver1 = dir |> String.slice(start_pos..-1) |> Version.parse!()
          ver2 = saved_dir |> String.slice(start_pos..-1) |> Version.parse!()

          case Version.compare(ver1, ver2) do
            :gt ->
              dir
            :lt ->
              saved_dir
            :eq ->
              [dir, saved_dir] |> Enum.random()
          end
        end)

        hex_beam_path = base_dir |> Path.join(hex_dir) |> Path.join(hex_dir) |> Path.join("ebin")
        Code.append_path(hex_beam_path)
      end
    end
  end
end
