我有一个使用fog-aws gem 将图像上传到AWS 的网站。当我在本地运行它时一切正常，但它不会部署到heroku。标准 heroku/ruby buildpack，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'

试过：1）当然，删除Gemfile.lock文件并捆绑安装几次2）明确包括formatador，使用旧版本（我认为错误消息不正确，因为formatador 0.2.5确实存在并且我可以安装它在本地和heroku上）3）使用'fog'而不是'fog-aws'（给我类似'unf'的错误，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 的顶部有一个“require 'fog/aws'”。在没有它的情况下在本地工作，但在部署到 heroku 时会导致上述行为。我添加了那条线，它起作用了。
