Use inquiry method on default string instead
user
```ruby
class Webpacker::Env
  DEFAULT = "production".freeze

  delegate :config_path, :logger, to: :@webpacker

  def self.inquire(webpacker)
    new(webpacker).inquire
  end

  def initialize(webpacker)
    @webpacker = webpacker
  end

  def inquire
    fallback_env_warning unless current
    current || DEFAULT.inquiry
  end

  private
    def current
      Rails.env.presence_in(available_environments)
    end

    def fallback_env_warning
      logger.info "RAILS_ENV=#{Rails.env} environment is not defined in config/webpacker.yml, falling back to #{DEFAULT} environment"
    end

    def available_environments
      if config_path.exist?
        YAML.load(config_path.read).keys
