Hello. I’m trying to install my first application with Phoenix.
I just installed elixir:
sudo apt-get install elixir
elixir -v returns me:
Erlang/OTP 24 [erts-12.2.1] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]
Elixir 1.12.2 (compiled with Erlang/OTP 24)
Then I did:
mix archive.install hex phx_new
sudo apt-get install inotify-tools
mix phx.new app --database mysql
cd app
mix deps.get
mix ecto.create
And I have this error:
==> phoenix
Compiling 69 files (.ex)
== Compilation error in file lib/mix/tasks/phx.gen.cert.ex ==
** (RuntimeError) error parsing file /usr/lib/erlang/lib/public_key-1.11.3/include/OTP-PUB-KEY.hrl, got: {:error, :enoent}

could not compile dependency :phoenix, "mix compile" failed. You can recompile this dependency with "mix deps.compile phoenix", update it with "mix deps.update phoenix" or clean it with "mix deps.clean phoenix"
Why ?
Thanks.
Hey @stephweb welcome! Unfortunately the way the package managers on linux have structured Elixir / Erlang it’s really easy to get a “partial” install that doesn’t really have many of the things that you need.
Most folks are using GitHub - asdf-vm/asdf-erlang: Erlang plugin for asdf version manager and GitHub - asdf-vm/asdf-elixir: Elixir plugin for asdf version manager as a way to install Erlang / Elixir, which also makes it easy to use the latest versions of each.

I wish there was an easier way to do this.
I don’t know if this helps as in my learning path I have not yet reached phoenix but I’m also running on 22.04 (Lubuntu) and installed Elixir this way (an Ansible play but you should be able to “play” it manually without problems).
Erlang from Ubuntu repos and latest (at the moment when i made the installation) Elixir compiled against the correct Erlang version from Github releases.
$ cat roles/elixir/tasks/main.yml

I’ve found that you can do it with apt and system packages. Just do the following:
sudo apt install erlang-dev
I found this solution by looking for the file in question in Google, namely OTP-PUB-KEY.hrl
and finding the package on the Ubuntu repository: https://packages.ubuntu.com/jammy/all/erlang-dev/filelist
Hope that helps!
