如用户手册中所述

您需要将AWS凭据设置为heroku中的配置变量（基本上是环境变量）。您可以检查它们是否设置了heroku配置；如果未设置它们，您可以使用heroku config:set S3\u BUCKET\u NAME=something AWS\u ACCESS\u KEY\u ID=which AWS\u SECRET\u ACCESS\u KEY=something\u SECRET添加它们。heroku配置的更多信息--帮助

在AWS改变策略要求IAM用户后，我也遇到了同样的问题。我创建了新的IAM用户并收到了IAM用户的新凭据，在使用新凭据更新我的应用程序后，我收到了相同的错误。我通过返回AWS、服务、IAM用户并为用户创建管理员访问权限来修复它。

哪一行是第13行？S3连接在哪里？显然，您使用Heroku是因为它在您的标记中，但是您的环境变量设置了吗？请提供更多关于你的情况的信息，因为其他人已经有了，所以不允许我编辑。第13行：如果@profile.save，我想你就是那个人是的，我编辑它是为了改进格式和问题标题。您可以进行其他编辑，尽管您需要将AWS凭据设置为heroku中的配置变量（基本上是环境变量）。您可以检查它们是否设置为

heroku config

；如果未设置它们，您可以使用heroku config:set S3\u BUCKET\u NAME=something AWS\u ACCESS\u KEY\u ID=which AWS\u SECRET\u ACCESS\u KEY=something\u SECRET添加它们。有关heroku config--help的更多信息，请参见。您可以接受自己的答案，因为问题提出已经48小时了。我已经为你在这里引用的评论附上了引文。为了使这篇文章更具信息性，也许你也可以编辑使用这种方法的工作内容，这样那些在将来找到这篇文章的人将有更好的机会解决他们的问题。
