我尝试将图片合并到我的网络应用中,并在删除了一些功能后继续遇到此错误。它归结为我的创造'应用程序控制器,我不完全确定我应该从哪里开始。

修改您的Gemfile的aws-sdk以安装2.0之前的版本:

gem 'aws-sdk', '< 2.0'

此问题是在新版本的aws-sdk(2.0+)中引入的。您可以在此处阅读更多内容:http://ruby.awsblog.com/post/TxFKSK2QJE6RPZ/Upcoming-Stable-Release-of-AWS-SDK-for-Ruby-Version-2

有官方解决方案 使用此分支的回形针: 它适用于2以上的aws-sdk版本

gem 'paperclip', :git=> 'https://github.com/thoughtbot/paperclip', :ref => '523bd46c768226893f23889079a7aa9c73b57d68'

只需将s3_region参数添加到您的回形针s3配置

适合我

答案 2 :(得分:4)

我通过导航到我的gem文件夹并将Gems更改为:

来实现它
  • gem'paperclip'
  • gem'aws-sdk'

可以删除版本声明。

为避免获得gem.lock error,请运行bundle update而不是bundle install,否则只会更新宝石。

现在,heroku logs -t命令可用于监控heroku服务器以映像上传。

我在AWS服务器上收到了一个新错误Access Denied Error

要解决此问题,我在亚马逊网站上找到了Active Access Key ID最新日期,并使用heroku命令输入最新的Access key IDSecret access key

这使我能够在heroku上查看我的图像。

我已经做了很多Access key IDSecret access keys尝试解决问题,但发现Gems是真正的问题。

提示:将所有访问密钥信息保存到OneNote,记事本等。这样您就可以返回并检查它们。

Paperclip用于在版本4.3和下面使用AWS-SDK v1。他们正在尝试包含AWS-SDK v2

官方升级文件https://github.com/thoughtbot/paperclip/blob/master/UPGRADING

##################################################
#  NOTE FOR UPGRADING FROM 4.3.0 OR EARLIER       #
##################################################

Paperclip is now compatible with aws-sdk >= 2.0.0.

If you are using S3 storage, aws-sdk >= 2.0.0 requires you to make a few small
changes:

* You must set the `s3_region`
* If you are explicitly setting permissions anywhere, such as in an initializer,
  note that the format of the permissions changed from using an underscore to
  using a hyphen. For example, `:public_read` needs to be changed to
  `public-read`.

由于一些向后无法比较(阅读此https://github.com/thoughtbot/paperclip/issues/2021)这已合并但尚未正式发布,但应在Paperclip v 5.0.0

中发布

就像提到的Vitali Mogilevsky一样,你现在必须使用它:

# Gemfile
# ...
gem 'paperclip', :git=> 'https://github.com/thoughtbot/paperclip', :ref => '523bd46c768226893f23889079a7aa9c73b57d68'

发布Paperclip 5.0时,应包含AWS-SDK v2
