安装 aws-sdk-3 后无法启动 Rails 服务器

Question

我知道有很多这样的问题，但我相信我的情况略有不同。 我最近决定在我的 rails 版本 3 项目 (RUBY_VERSION - 1.9.2p320) 中构建一个 AWS-S3 gem。 成功安装 aws-sdk gem 后，我在rails server上收到一条错误消息

我都试过了

gem 'aws-sdk', '~> 3'

和

gem 'aws-sdk-s3', '~> 1'

我已经检查了 github 中提到的模块，但有什么要了解的。 我究竟做错了什么？ 非常感谢。 任何帮助将不胜感激。

Answer 1

我认为根据您在问题中发布的参考模块很清楚。 如果您看到代码new_transport_request方法在module Ruby_2 （第 30 行）和module Ruby_1_9_3 （第 83 行）中定义，然后如果您看到第 19 到 24 行：

if RUBY_VERSION >= '2.0'
  Net::HTTP.send(:include, Ruby_2)
  Net::HTTP::IDEMPOTENT_METHODS_.clear
elsif RUBY_VERSION >= '1.9.3'
  Net::HTTP.send(:include, Ruby_1_9_3)
end

ruby 1.9.2 没有 if 条件。 总之，问题不是来自 Ruby 或 Rails，而是来自不支持 ruby 1.9.2 的 gem。

您可能只需upgrade the ruby to 1.9.3解决此问题。 此外，ruby 1.9.2 不再维护，因此最好升级以避免安全漏洞。 我希望它有帮助。

谢谢你。

我将从更新最新的 rails 开始，但当然是渐进式的。 ActiveStorage 功能更改和最新的 gem。 不知道自 Rails 3 以来发生了什么
