为Paperclip正确配置了S3凭据：

我确实看到了Heroku UI中设置的环境变量，我可以很好地上传照片。

但是，当我尝试在生产中销毁给定模型时，我在日志中收到此错误：

AWS::Errors::MissingCredentialsError

这一切在本地也很好（显然使用不同的S3存储桶）。有什么问题？为什么即使上传工作正常，我也只是在生产中{{1}}？

您可能希望确保您使用的是aws-sdk gem v1而不是aws-sdk v2。日志使它看起来像你在v1（＆＃34; AWS ::＆＃34;） - 如果你在aws-sdk v2上，回形针不会起作用。不要以为thinkbot会继续支持它，我建议你研究使用jquery-file-uploader（https://devcenter.heroku.com/articles/direct-to-s3-image-uploads-in-rails#pre-signed-post）直接上传到s3 - 注意文章没有显示aws-sdk-v2说明。下面链接的答案确实使用了aws-sdk-v2：

Rails direct to S3 upload using aws-sdk gem and jQuery-File-Upload on heroku

可以使用Paperclip和AWS S3上传但不能删除Heroku上的图像
