我'd like to upload image from iOS to S3 through Heroku by paperclip. I'已使用本网站作为参考 . https://devcenter.heroku.com/articles/paperclip-s3
但是，它返回错误“状态代码：500， Headers ” . 我不确定是什么问题 . 我期待着您的回音 .

日志
我检查了heroku日志，然后说了以下内容 .

这个链接告诉我，我需要降级aws-sdk的版本 . NameError (uninitialized constant Paperclip::Storage::S3::AWS):
gem 'aws-sdk', '< 2.0'

这是你的错误：
在线查看之后，这基本上是由没有定义
AWS模块的aws-sdkv2宝石引起的 . 简而言之，这意味着Paperclip无法调用将其数据保存到S3所需的模块 .解决方法是将
aws-sdk版本降级为1：...但是，谁喜欢变通方法呢？
你应该能够让它运作起来pull from the Paperclip master branch：
