"could not compile dependency :dns" error when running mix ecto.create

[LuySeiwert]

Environment

OS: Ubuntu 22.04
Erlang version: 23.3 installed via asdf (only possible thanks to this workaround asdf-vm/asdf-erlang#247 (comment))
Elixir version: 1.14.3-otp-23 installed also via asdf

Steps to reproduce

Inside the reticulum repository
mix deps.get
mix ecto.create

Expected Outcome

That it works.

Actual outcome

could not compile dependency :dns error

Things I tried to resolve this issue

• googling the issue, I didn't find anything, there are other people having this type of error but never with this specific library or project
• looking at the closed issues in this repository, there are two similar issues Error with mix ecto.create #24 Error running mix ecto.create #18, I tried their fixes, they didn't work for me (still got the same error message both times)

Any idea why this is happening?

Environment:

• Mac os ventura

Unfortunately, your suggestion didn't work, I still got the same error, but I was able to resolve this issue.

I noticed you are using Mix 1.14.4, which I found odd, as when I initially used a different elixir and erlang version than the ones prescribed I got errors saying that the elixir version specified in the .tools-version file (elixir 1.14.3) does not match the one I installed. I thought you weren't supposed to change this file as your guide says to be careful about the version of elixir and erlang.

When I tried setting the elixir version to 1.14.4 in this .tools-version file (which didn't solve anything), I saw that the specified erlang version is 23.3.4.18. So I installed that specific version and stuck to elixir 1.14.3, which gave me a different compile error now with a hackney dependency. However, for this, I found other GitHub issues telling me to update the rebar dependency via mix local.rebar and that worked.

Thanks for your help, I would not have noticed the difference in erlang versions if I hadn't seen you using elixir 1.14.4!
