heroku部署失败，出现fog-aws (显示formatador“已删除”)

Question

我有一个网站上传图像到AWS使用fog-aws。当我在本地运行它时，一切工作正常，但它不会部署到heroku。标准heroku/ruby构建包，所有内容的最新版本：

ruby 2.5.1，rails 5.2.2，gem 'carrierwave'，'1.3.1‘gem 'fog-aws'，'3.3.0’

尝试: 1)当然，多次删除安装的Gemfile.lock文件和包2)显式包含了formatador，使用旧版本(我不认为错误消息是正确的，因为formatador 0.2.5确实存在，我可以在本地和heroku上安装它) 3)使用'fog‘而不是'fog-aws’(给我类似的错误与'unf'，并包含大量不必要的依赖项)

弄清楚了；只需要RTFM！

我需要在config/initializers/fog.rb的顶部添加"require 'fog/aws'“。在没有它的情况下在本地工作，但在部署到heroku时导致了上面的行为。我添加了这一行，它起作用了。
