Ruby on rails Rails 3 Capistrano部署错误（在…处解析块节点）

我正在尝试使用capistrano将rails 3.2.11应用程序部署到bluehost共享主机上。我一直在犯这个错误

我环顾四周，可能是YAML解析错误。 因此，我尝试在irb中使用它来查看是否有任何

.yml

文件导致了问题

YAML.load_file("filename.yml")

但结果都很好

这是我的档案，如果需要的话

gem 'rails', '3.2.11'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'devise'
gem 'friendly_id', "~> 4.0.9"#, :git => "git://github.com/norman/friendly_id.git"
gem 'simple_form'
gem 'json'
gem 'cancan'
gem 'rqrcode-rails3' #imageqrcodes
gem 'mini_magick'
gem "breadcrumbs_on_rails"

group :production do
  gem 'pg'
  # gem 'thin' # Server used in production
end

group :development, :test do
  gem 'mysql2'
  gem 'capistrano'
  gem 'rvm-capistrano'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
  gem 'twitter-bootstrap-rails'
  gem 'execjs', '1.4.0'
  gem 'therubyracer', :platforms => :ruby
end

gem 'jquery-rails'

问题是在我的

数据库.yml

文件中。我的密码以一个符号开头。我找不到逃避它的方法，所以我改变了它，现在它就像一个符咒一样工作。

可能是

rake

版本的问题。您可以运行任何rake命令而不出错吗？尝试运行

rake db:migrate:status

YAML:：load（ERB.new（IO.read（path[“config/database”].first））.result）在irb？@AmirF中它说

namererror:uninitialized constant ERB

我想我已经发现了问题，

第18行第13列的block节点是指我的数据库密码。由于密码中有很多符号，YAML无法解析它。我试着在它们周围加上双引号，但仍然不起作用。有人知道解析yml文件中符号的正确方法吗？
