Additional context

Environment

Ruby Version: 3.3.5

Framework Version (Rails, whatever): 7.1

Anyway Config Version: 2.6.4

How do you load the gem? You must load it via the require "anyway_config" to setup the load path properly (so the Ruby 3.4+ files are not loaded in Ruby 3.3).

Does the following command work for you as below?

$ ruby -v
ruby 3.3.5 (2024-09-03 revision ef084cc8f4) [arm64-darwin23]

$ TEST_FOO__BAR=1 ruby -ranyway_config -e "puts Anyway::Config.for(:test)"

{"foo"=>{"bar"=>1}}

[le0pard]

It is not after load, it is output in docker environment after bundle install command

[palkan]

Hm, do you run something like bootsnap precompile then? (Or whatever else trying to read Ruby files)

[le0pard]

yes, this is command in docker:

RUN bundle install && \
    rm -rf ~/.bundle/ "${BUNDLE_PATH}"/ruby/*/cache "${BUNDLE_PATH}"/ruby/*/bundler/gems/*/.git && \
    bundle exec bootsnap precompile --gemfile

so yes, it can be warning from bootsnap command. But generated by this gem

[palkan]

Well, bootsnap precompile is a static tool, so there is hardly anything we can do here. Since the compiled file is not used in production, it's safe to disable warnings (to reduce the noise). Try something like `RUBYOPT=-W0".
