未初始化的常量 ActiveJob::Serializers

Question

我正在尝试更新旧的 Rails 应用程序以在 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，一切似乎都正确部署到 heroku，但是当我尝试启动应用程序时，出现以下错误：

gems/shopify-money-1.1.2/lib/money/rails/job_argument_serializer.rb:5:in 'module:Rails': uninitialized constant ActiveJob::Serializers (NameError)

我尝试重新加载数据库时收到更完整的错误消息：

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

其实是一样的。它似乎无法找到 ActiveJob::Serializers 即使 Rails 5.0.0 及更高版本应该有......帮助！

Answer 1

对此的早期摇摆。

是的，Rails 有

ActiveJob::Serializers

，我猜它只是 yet 在

shopify-money

加载时初始化。

我猜它在本地工作，因为

production.rb

有一些

development.rb

没有的东西试图加载这个宝石before

ActiveJob

.

要确认，您可以尝试在本地执行

RAILS_ENV=production rails console

。它应该以同样的方式失败。

至于修复，您的选择是推迟加载 gem 的

JobArgumentSerializer

，直到您确定所有 Rails 都已加载或执行相反的操作，并确保

require "active_job/serializers"

在任何

shopify-money

代码之前。

在

application.rb

，我希望看到这样的东西：

require "rails" #<- all of Rails, including ActiveJob
...
Bundler.require(*Rails.groups) #<- requires the gems from your Gemfile

这确保所有的宝石都在 Rails 之后加载。

我猜你在初始化器或

production.rb

中有一些东西在加载

application.rb

文件之前尝试使用 gem.
