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，并且我正在关注他们的教程。然而，我试着用一个回形针插件连接到我的Amazon S3的桶，现在和进出口收到此错误：

ArgumentError in Images#index

Showing app/views/images/index.html.erb where line #19 raised:

我的文件是这样的：

1）应用程序/模型/ image.rb

class Image < ActiveRecord::Base
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"
end

2）配置/ s3.yml

bucket: (MY BUCKET HERE)
access_key_id: (MY ACCESS KEY ID HERE)
secret_access_key: (MY SECRET ACCESS KEY HERE)

我怎样才能得到它的工作？

C：/Ruby/lib/ruby/1.8/yaml.rb：133：in load' - 这是一个YAML错误。你可能有一个格式不正确的YML文件。在脚本/控制台 试试这个代码：

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

下面是我的工作配置的例子：

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" 

而且YML文件：

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

你是对的。我的'e'文本编辑器以一种奇怪的格式保存了yaml文件，并添加了一些额外的字符。一切正在工作。谢谢！
