Getting compile errors after adding ex_doc dependency

Questions / Help
1

I added the ex_doc dependency to my mix.exs, did a mix deps.get, and mix.compile and I’m getting a compile error. Am I missing something here?

% cat mix.exs
defmodule Issues.MixProject do
  use Mix.Project

  def project do
    [
      app: :issues,
      escript: escript_config(),
      version: "0.1.0",
      elixir: "~> 1.7",
      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
    [
      {:httpoison, "~> 1.4.0"},
      {:poison, "~> 4.0"},
      {:ex_doc, "~> 0.19.0"}
    ]
  end

  defp escript_config do
    [
      main_module: Issues.CLI
    ]
  end
end

% mix deps.get

That’s a know issue we’re working on fixing, here’s a workaround before there’s a new makeup version: https://github.com/elixir-lang/ex_doc/issues/938#issuecomment-446551764

I pinned the nimble_parsec version to 0.4.0, as the workaround suggested, and it worked.

{:nimble_parsec, “~> 0.4.0”, only: :dev, override: true}

Thanks, much!
