I’m working my way through Engineering Elixir Applications and I’m running into an issue that I hope is something easy. I’m on page 103 if anyone else has the book. Workstation used for running through the examples: M1 Mac.
When running the Github Action it fails with the following:
Run mix dialyzer --format github

From the book I’ve setup the following workflow (ci_cd.yaml below, as of page 103 for those that have it).

As seen above this Workflow runs-on: ubuntu-latest. From the Workflow errors we’re calling for a file in the path of /opt/homebrew/Cellar/ and failing, because this isn’t macOS (I’m unaware of another homebrew tool)
In my .gitignore I have the following:
# Local .terraform directories
**/.terraform/*
# .tfstate files
*.tfstate
*.tfstate.*
# Crash log files
crash.log
crash.*.log
# Exclude all .tfvars files, which are likely to contain sensitive data, such as
# password, private keys, and other secrets. These should not be part of version
# control as they are data points which are potentially sensitive and subject
# to change depending on the environment.
*.tfvars
*.tfvars.json
# Ignore override files as they are usually used to override resources locally and so
# are not checked in
override.tf
override.tf.json
*_override.tf
*_override.tf.json
# Include override files you do wish to add to version control using negated pattern
# !example_override.tf
# Include tfplan files to ignore the plan output of command: terraform plan -out=tfplan
# example: *tfplan*
# Ignore CLI configuration files
.terraformrc
terraform.rc
# Typical Elixir ignore files
/_build

/.fetch
erl_crash.dump

/config/*.secret.exs
.elixir_ls/

/priv/plts/*.plt.hash
So - I’d expect deps and _build cache to not be present (and they aren’t in my repo). When I search for Cellar in my local (macOS) working directory grep -Rnw ‘.’ -e ‘Cellar’ I see:

Spot checking ./deps/erlex/src/erlex_parser.erl:7 I see:
-module(erlex_parser).

unwrap({_,_,V}) -> V.
-file("/opt/homebrew/Cellar/erlang/26.2.5/lib/erlang/lib/parsetools-2.5/include/yeccpre.hrl", 0).
I’m a little lost on how my dialyzer.run via Github action is failing with the missing file error. If the ubuntu-latest is downloading / building the dependancies on that virtual machine then how is it failing / looking for Cellar/homebrew file locations? As shown above when I search from the root of my project I’m only seeing the matching results in my _build and deps folders - which are excluded.
Happy to add snippets of other files or anything to help me track this down. Thanks for the time if you’ve made it this far.
