“在架构中找不到环境数据。” 在Rails 6上反复调用黄瓜时使用数据库清理程序

注意：这不是对Rails 5的重复，Rspec：尽管在架构中找不到环境数据，但它是相似的。受影响的版本不同，解决方案对我不起作用。

我的Rails设置如下：

• Rails 6.0.1
• 黄瓜栏杆2.0.0
• database_cleaner 1.7.0

每当我cucumber第二次或以后运行时，都会出现此错误：

3924 ~/fork/my-proj$ bundle exec cucumber
rails aborted!
ActiveRecord::NoEnvironmentInSchemaError: 

Environment data not found in the schema. To resolve this issue, run: 

        rails db:environment:set RAILS_ENV=test

我该如何摆脱呢？

如果我运行rails db:environment:set RAILS_ENV=test，它将在下一次运行时将其删除cucumber，但在此之后它将始终重新运行。

我发现了另一个建议将其添加到我的配置中的答案，但是它什么也没做：

# This did NOT fix my problem:
DatabaseCleaner.clean_with(
  :truncation,
  except: %w(ar_internal_metadata)
)

显然database_cleaner正在删除环境数据，但是我不知道如何停止它。

谁能帮我摆脱这个烦人的警告？
