Ruby AWS SDK错误。模块\u可继承\u attributes.rb中的值nil

我有以下脚本：

require 'httparty'
require 'aws-sdk-s3'

include HTTParty

Aws.config.update({
  region: 'us-east-1',
  credentials: Aws::Credentials.new('...', '...')
})

client = Aws::S3::Resource.new
movies = self.class.get("#{HOST}/movies")

运行时，我遇到以下错误：

Traceback (most recent call last):

在阅读了AWS的文档和教程之后，我仍然找不到这个问题。有什么问题吗？

我发现问题出在

include HTTParty

这一行。我在那行之前声明了S3客户机，现在它可以工作了：

require 'httparty'
require 'aws-sdk-s3'

Aws.config.update({
  region: 'us-east-1',
  credentials: Aws::Credentials.new('...', '...')
})
client = Aws::S3::Resource.new

include HTTParty

movies = self.class.get("#{HOST}/movies")
