I’m still learning Elixir,and am making a basic elixir program to call a function from a python program. I am attempting to use erlport to do so. However, in the code below Erlport is undefined. I don’t see what could be causing it.

defmodule RarFile do
  @moduledoc """
  Documentation for `RarFile`.
  """

  @doc """
  Hello world.

  ## Examples

      iex> RarFile.hello()
      :world

  """
  

  def extractor(filepath) do
    {:ok, pid} = :erlport.open_port({:spawn, "python"}, [:binary, :stream, packet: 4])


  end

end

Here is the mix.exs file that I’m using.

defmodule RarFile.MixProject do
  use Mix.Project

  def project do
    [
      app: :rar_file,
      version: "0.1.0",
      elixir: "~> 1.14",
      start_permanent: Mix.env() == :prod,
      deps: deps()
    ]
  end

  # Run "mix help compile.app" to learn about applications.
  def application do
    [
      extra_applications: [:logger]
    ]
  end

  # Run "mix help deps" to learn about dependencies.
  defp deps do
    [

      {:erlport, "~> 0.10"}
      # {:dep_from_hexpm, "~> 0.3.0"},
      # {:dep_from_git, git: "https://github.com/elixir-lang/my_dep.git", tag: "0.1.0"}
    ]
  end
end
