' ``` ### 試したこと ① https://github.com/rails/rails/issues/32933 こちらの情報をもとに、config/initializers内、config/application.rb、config/environment/production.rbを確認しました。 initializers内でモデルを呼び出しているのはこちらで追加したconfig/initializers/carrierwave.rbになりますがこちらを全てコメントアウトしてrails c -e productionを実行しても変わりませんでした。 ```ruby CarrierWave.configure do |config| config.fog_credentials = { provider: 'AWS', aws_access_key_id: 'hoge', aws_secret_access_key: 'hogehoge', region: 'hogehogehoge' } config.fog_directory = 'hoge-backet' config.asset_host = "https://hogehogehoge.com" config.cache_storage = :fog CarrierWave::SanitizedFile.sanitize_regexp = /[^[:word:].\-+]/ end ``` initializersは基本的にデフォルトで、新規で追加したのは上記のcarrierwave.rbのみになります。 ②active_storageの読み込みを無効化 active_storageを使用していないため、application.rb下記のように変更してactive_storageを無効化した結果、エラーが変化しました。 ```ruby //application.rb require_relative 'boot' require "rails/all" Bundler.require(*Rails.groups) module PwaApp class Application < Rails::Application config.load_defaults 5.2 config.time_zone = 'Tokyo' config.active_record.default_timezone = :local end end ``` ```ruby //application.rb require_relative 'boot' require "rails" require "active_model/railtie" require "active_job/railtie" require "active_record/railtie" require "action_controller/railtie" require "action_mailer/railtie" require "action_view/railtie" require "action_cable/engine" require "sprockets/railtie" require "rails/test_unit/railtie" module PwaApp class Application < Rails::Application 　　#省略 end end ``` ``` /home/ysuzuki/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/activerecord-5.2.1/lib/active_record/dynamic_matchers.rb:22:in `method_missing': undefined method `mount_uploader' for # (NoMethodError) from /var/www/rails/pwa_app/app/models/catalog/product_image.rb:3:in `' from /var/www/rails/pwa_app/app/models/catalog/product_image.rb:2:in `' from /var/www/rails/pwa_app/app/models/catalog/product_image.rb:1:in `

' ここまで上記エラーの※と同一の内容 ``` モデルのcarrierwaveのメソッドでエラーが起きるのですがstaging環境ではこちらで正常に動いていますので、メソッド名の誤りはないかと思います。 ```ruby //product_image.rb module Catalog class ProductImage < Catalog::Base mount_uploader :image, ProductImageUploader belongs_to :product end end ``` ### 補足情報 ruby 2.4.1 rails 5.2.0 carrierwave 1.1.0
