我正在尝试更新一个旧的Rails应用程序，以便在heroku-20堆栈上运行。我正在运行Rails 5.1.1和shopify-money 1.1.2。它在本地工作，一切似乎都正确地部署到heroku，但当我尝试启动应用程序时，我得到以下错误：
gems/shopify-money-1.1.2/lib/money/rails/job_argument_serializer.rb:5:in 'module:Rails': uninitialized constant ActiveJob::Serializers (NameError)
当我尝试重新加载数据库时，我得到一个更完整的错误消息：

heroku run bundle exec rake db:reload -a kiddocloud-staging
Running bundle exec rake db:reload on ⬢ kiddocloud-staging... up, run.3483 (Eco)

这是一回事。它似乎找不到ActiveJob：：Serializers，即使Rails 5.0.0及更高版本应该有...救命啊！
编辑：以下是我的application.rb的内容：

require_relative 'boot'

require 'rails/all'

Shopify/money初始化器文件（/config/initializers/shopify_money.rb）：

Money.configure do |config|
  config.default_currency = Money::Currency.new("USD")
end

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"

最终编辑：
尽管Chiperific尽了最大的努力，但似乎没有任何效果。我终于有了一个灵感，也许Shopify/Money gem对于我正在使用的Rails版本来说更新得太多了。我把它降到了0.16.0，成功了！由于其他原因，我仍然无法在本地启动和运行生产，但是当我部署到Heroku测试站点时，它工作了！我将在不久的某个时候再次升级Rails，并重新访问新版本的Shopify/Money。
