Hello, I’m a newcomer to both Elixir and Erlang and I’ve run into an issue and I hope someone here can help me. When using mix compile I seem to be getting a compatibility error, that the beam file is compiled for a later version of the runtime system. 16:05:42.441 [error] beam/beam_load.c(184): …

After some further debugging it seems luerl might be the issue. When I pin it to 1.1.0 I have no issue.

[image] nahoj: I use asdf to manage elixir/erlang. You need to use an Elixir version with -otp-25 suffix if you use Erlang version 25.

[image] LostKobrakai: should generally work. Should work or maybe could work? Should sounds like it’s supported and therefore such behaviour looks like a bug. I guess it could work, but since it’s not supported it’s recommended to make an update in order to avoid such problems now and in the …
