Here’s a repo with an example GitHub - brandynbennett/dialyzer_polyn_issue · GitHub

I’ve made a library called “polyn” and am trying to include it an my app. However my app uses dialyzer and won’t pass anymore and I can’t figure it out. I’ve done mix deps.clean --all && mix deps.get && mix deps.compile I’ve done mix dialyzer.clean . None of that seems to help. Same thing happens on a brand new project. Something about the library seems to be off. The error dialyzer gives me when I run mix dialyzer.build is

dialyzer.run error: Analysis failed with error:
Could not scan the following file(s):
  Could not get Core Erlang code for: dialyzer_polyn_issue/_build/dev/lib/polyn/ebin/Elixir.Polyn.Tracing.beam
dialyzer_polyn_issue/_build/dev/lib/polyn/ebin/Elixir.Polyn.beam
...every module in the library

When I look inside _build/dev/lib/polyn/ebin/ I see all the *.beam files so I don’t understand why it can’t get them. Using versions:

erlang 25.1
elixir 1.14.0-otp-25
