How do I recompile rebar3 with an Erlang/OTP 25 compiler? Running Elixir 1.13.4

Question

I´m following the free screencast / tutorial in Phoenix LiveView Starter But I´m not even able to start, as mix setup fails with:

=ERROR REPORT==== 6-Jul-2022::12:47:58.702361 ===

Elixir 1.13.4 (compiled with Erlang/OTP 24)

My mix.exs deps looks like this:

  defp deps do
    [
      {:phoenix, "~> 1.5.13"},
      {:phoenix_ecto, "~> 4.4"},
      {:ecto_sql, "~> 3.4"},
      {:postgrex, ">= 0.0.0"},
      {:phoenix_live_view, "~> 0.16.4"},
      {:floki, ">= 0.30.0", only: :test},
      {:phoenix_html, "~> 3.0.4"},
      {:phoenix_live_reload, "~> 1.2", only: :dev},
      {:phoenix_live_dashboard, "~> 0.4"},
      {:telemetry_metrics, "~> 0.6"},
      {:telemetry_poller, "~> 1.0"},
      {:gettext, "~> 0.11"},
      {:jason, "~> 1.0"},
      {:plug_cowboy, "~> 2.0"},
      {:faker, "~> 0.17.0"},
      {:number, "~> 1.0"}
    ]
  end

I´m not sure how I can recompile with an OTP 25 compiler. I´m running Elixir 1.13.4. It´s compiled with OTP 24. Not sure if that has anything to do with it? I´ve also tried mix local-rebar --force and mix deps.update telemetry without any luck.

Answer 1

If you’d examine the elixir --version prompt carefully, you’ll spot this:

Elixir 1.13.4 (compiled with Erlang/OTP 24)

Assuming you use asdf as the version manager, make sure you have the proper elixir version installed:

$ asdf list all elixir
...
1.13.4
1.13.4-otp-22
1.13.4-otp-23
1.13.4-otp-24
1.13.4-otp-25
...

You need the one, compiled with OTP25, meaning

$ asdf install elixir 1.13.4-otp-25
$ asdf global elixir 1.13.4-otp-25

would do.

Also asdf plugin add elixir could be required if it's the first time asdf is installed – Hakon

Also, on macOS, need to add "export PATH=~/.asdf/shims:$PATH" into "/.zshrc" – Hakon

Replacing Elixir with a version compiled by Erlang/OTP 25 did not quite do the trick for me. I had to also reinstall rebar. Which I guess was what the message told me in the first place...

I instead downgraded homebrew's erlang package:

$ brew uninstall --ignore-dependencies erlang
$ brew install erlang@24
$ PATH="/opt/homebrew/opt/erlang@24/bin:$PATH"
$ elixir --version
Erlang/OTP 24 [erts-12.3.2.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [dtrace]

Looks like OTP 25 is not quite ready with Elixir. There is a open issue for OTP 25 support.

This is by no means an issue for OTP25 support. Elixir is perfectly ready for OTP25. – Metonym
