RoR：无法将回形针连接到 Amazon S3

我决定将我的应用程序部署到 Heroku，我正在学习他们的教程。但是，我现在尝试使用回形针插件连接到我的 Amazon S3 存储桶，但出现此错误：

图像中的参数错误#index

显示第 19 行出现的 app/views/images/index.html.erb：

第 0 行第 39 列的语法错误：`bucket: (MY BUCKET HERE)
access_key_id：（此处为我的访问密钥 ID）
secret_access_key：（我的秘密访问密钥）

我的文件如下所示：

1) app/models/image.rb

类图像 has_and_belongs_to_many :pairs
validates_presence_of :img_file_name
has_attached_file :img, :styles => {:thumb=> "100x100#", :page => "400x320>"}, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml "
结束

2) 配置/s3.yml

桶：（我的桶在这里）
access_key_id：（此处为我的访问密钥 ID）
secret_access_key：（我的秘密访问密钥）

我怎样才能让它工作？

C:/Ruby/lib/ruby/1.8/yaml.rb:133:in load' - 这是 YAML 错误。您可能有一个格式错误的 YML 文件。 在您的脚本/控制台中尝试此代码：

require 'yaml'
my_hash = YAML::load File.read("#{RAILS_ROOT}/config/s3.yml")

以下是我的工作配置示例：

  has_attached_file :data,
  :styles => {
    :small => "100x100#",
    :medium => "400x400#",
    :large => "640x480#"
  },
  :storage => :s3,
  :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
  :path => ":attachment/:id/:style.:extension",
  :bucket => "xxx"

还有yml文件：

development:
  access_key_id: ***
  secret_access_key: ***

你是对的。我的“e”文本编辑器将 yaml 文件保存为带有一些附加字符的奇怪格式。现在一切正常。谢谢！
