我知道已经有人问过这类问题。

我使用s3gem 将我的文件上传到s3存储桶中。但是在s3gem 安装之后，当我启动 rails server 时，它会显示这个错误：

有谁知道，如何解决这个错误？我应该尝试其他宝石吗？

是的，我刚刚遇到这个问题并解决了。这是因为 AWS 将他们的 gem 更新到了 2.0。如果根据他们发布的这篇文章将 gem 更新到 2.0，则需要不同的配置。

如果您想使用之前的版本，只需更改 Gemfile，如下所示：

宝石文件

宝石'aws-sdk'，'< 2.0'

今天早上我们遇到了同样的问题。我们已经安装了这个 aws-sdk gem，但是昨天它更新到了第 2 版。似乎版本 2 不再解决此问题，所以我建议使用最新版本 1：1.61.0
