I have debian and manjaro linux for daily use, Hex can not be found only appeared under debian, it can be found under manjaro. They have the same networking configuation, i use git proxy and hex.pm mirror for both.

Precheck

  • Do a quick search and make sure the issue has not yet been reported
    yes, i searched, but not working.

  • Do not use the issues tracker for guidance, questions or support (try Elixir Forum, Stack Overflow, Slack, etc. instead)
    yes, not working.

  • If using a client other than VS Code, please try VSCode's "ElixirLS: Elixir support and debugger" extension. Does it reproduce your failure?
    yes.

Environment

Current behavior

can not find hex under debian12.5

due to gfw, i need to use mirror to access repo.hex.pm, and also i need to use proxy for git.

my hexpm mirror, according https://hex.pm/docs/mirrors

export HEX_UNSAFE_HTTPS=1
export HEX_MIRROR="http://hexpm.upyun.com"

my git mirror

git config --global http.proxy socks5://127.0.0.1:1080
git config --global https.proxy socks5://127.0.0.1:1080

i download hex manually

https://hexpm.upyun.com/installs/1.14.0/hex-2.0.6.ez
https://repo.hex.pm/installs/1.14.0/hex-2.0.6.ez

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
$ mix hex.info                      
Hex:    2.0.6
Elixir: 1.14.0
OTP:    25.2.3

Built with: Elixir 1.14.2 and OTP 23.3

aaa

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")

i had installed hex, but plugin can not find it.

Expected behavior

hex can be found by elixir-ls

same behavior for astronvim

i checked the code of elixir-ls

Mix.Hex.ensure_installed?(true)

but i don't know where is the definition, how it works, i need to know it to check my configuration.

lukaszsamson commented

This code calls a function in elixir standard lib

ziyouchutuwenwu commented

Mix.Hex.ensure_installed? seems to be like this

@spec ensure_installed?(boolean) :: boolean
  def ensure_installed?(force?) do
    cond do
      Code.ensure_loaded?(Hex) -> true
      force? or install_hex?() -> Mix.Tasks.Local.Hex.run(["--force"])
      true -> false
    end
  end

and the install.exs from vscode plugin look like this

aaa

so confused, elixir environment is just quite simple

apt install elixir
mix local.hex

I'm not sure it is caused by my configurtion, i reinstall debian, only install these

vscode
apt install elixir -y
proxychains
proxychains mix local.hex

create demo project

mix new demo

open with vscode, logs
aaaaaaaa

i have no idea about it.

ziyouchutuwenwu commented

it seems to be working, need a bit change of code

scripts/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

line 342

load_hex()
cond do xxx

making symbolic connection to system lib seems to be the easiest way, no need to change anything

sudo ln -s ~/.mix/archives/hex-2.0.6/hex-2.0.6 /usr/lib/elixir/lib/hex

I'm going to close it. The issue seems specific to OP's system and it's solved in their case
