启动 Rails 开发服务器时出现错误。我运行 rails 3.0.6 和 ruby​​ 1.8.7 (2012-06-29 patchlevel 370) [i686-linux]

我执行 rails 时控制台输出是这样的

=> Booting Mongrel
=> Rails 3.0.6 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
host is not a valid option for Mongo::Connection

我主要关心的是这个错误“主机不是 Mongo::Connection 的有效选项”。我集成了 devise 1.5.2 以通过 Omniauth 运行 Facebook、Twitter 和 LinkedIn 登录，现在出现了这个 mongoDB 错误。

我在这个 Rails 应用程序中使用的 GemFile。

source 'http://rubygems.org'

gem 'rails', '3.0.6'
gem 'rake', '0.8.7'

gem 'mysql'
gem 'mysql2', "0.2.11"

gem 'mongrel'
gem 'jquery-rails', '>= 0.2.7' 
gem 'active_scaffold_vho' 
gem 'inherited_resources', '~> 1.2.1'

gem 'json_pure' 
gem 'formtastic', '~> 1.2.3' 
gem "devise", "1.5.2"
gem 'omniauth'
gem 'omniauth-twitter'
gem 'omniauth-facebook'

gem 'rack-ssl'
gem 'state_machine'

gem "http_accept_language", '~> 1.0.2'

gem 'recurly', '~> 2.1.0'
gem 'newrelic_rpm'

group :test, :development do
  gem 'rspec-rails', "~> 2.8"
  gem 'rspec-mocks', "~> 2.8"
  gem 'capybara', "~> 0.4.1.2"
  gem 'database_cleaner', "~> 0.6.7 "
  gem 'cucumber', "~> 0.10.2"
  gem 'spork', "~> 0.9.0"

  gem 'faker', "~> 0.9.5"
  gem 'email_spec'  
  gem 'rails-erd'  
  gem 'ruby-debug'
end

group :development do
  gem "hirb"
  gem "awesome_print"
end

mongoid.yml 文件如下：

defaults: &defaults
  host: localhost
  database: teenscrio

development:
  <<: *defaults
  database: teenscrio_dev

staging:
  <<: *defaults
  database: teenscrio_stg

test:
  <<: *defaults
  database: teenscrio_tst

# set these environment variables on your prod server
production:
  host: <%= ENV['MONGOID_HOST'] %>
  port: <%= ENV['MONGOID_PORT'] %>
  username: <%= ENV['MONGOID_USERNAME'] %>
  password: <%= ENV['MONGOID_PASSWORD'] %>
  database: <%= ENV['MONGOID_DATABASE'] %>

为什么现在出现这个错误？devise和mongoid有什么关系？我该如何解决这个问题？

它必须从 mongoid.yml 中删除

host: localhost

然后它不显示错误并且工作正常。

您需要重新考虑如何初始化Mongo::Connection. 您似乎在选项中错误地提供了主机，而它必须直接传递给初始化程序或在环境中指定。

我假设您的开发和生产环境在构建 MongoDB 连接的方式方面存在一些差异，这会导致您遇到异常。
