AWS-S3宝石，除非定义？ @@ {：instance_writer =＆GT;真} [英] aws-s3 gem unless defined? @@{:instance_writer=>true}

问题描述

我试图整合 AWS-S3 宝石和Rails的最新版本（4.1 .0），并启动服务器时，我收到此错误：

I am trying to integrate the aws-s3 gem with the latest version of Rails (4.1.0), and when starting the server I receive this error:

aws-s3-0.6.3/lib/aws/s3/extensions.rb:223:in `class_eval': ///.rvm/gems/ruby-1.9.3-p385/gems/aws-s3-0.6.3/lib/aws/s3/extensions.rb:223: syntax error, unexpected $undefined (SyntaxError) unless defined? @@{:instance_writer=>true}

有没有人有什么想法？

Has anyone got any ideas?

创业板的大部分尚未更新超过两年，所以我认为它可能最终会过时。

The bulk of the gem has not been updated for over two years so I am thinking that it may finally be out of date.

推荐答案

在Rails 4.1的错误发生，因为 cattr_attribute 从模块中删除。

In Rails 4.1 the bug is happening because cattr_attribute was removed from Module.

一个短期看在GitHub上的问题说，该项目已被放弃。

A short look at the issues in github say that the project has been abandoned.

您可能需要使用叉子一个像 https://github.com/bartoszkopinski/aws-s3 ，这解决了问题，或改变宝石的 https://github.com / AWS / AWS-SDK-红宝石。

You may want to use one of forks like https://github.com/bartoszkopinski/aws-s3, that fixes the issue, or change the gem to the https://github.com/aws/aws-sdk-ruby.
