Rails在environment.rb中未定义方法`Initialize’

Rails undefined method `Initialize' in environment.rb

我正在尝试将twitter / bootstrap集成到我的第一个rails应用程序中(遵循这篇文章http://www.opinionatedprogrammer.com/2011/11/twitter-bootstrap-on-rails/)，现在我收到此错误，我是无法理解/解决。

Talker::Application.initialize!

我对rails很新，所以任何帮助/方向都非常感谢！

按照naren的说明，您是否从environment.rb文件中删除了Rails.Initialize.run块？我知道这可能听起来很傻:)

此外，从第二个错误，我收集到您可能正在使用Mongo HQ，如果它是在Heroku上托管的，他们有一个非常详细的配置数据库的说明手册。 Heroku MongoHQ开发中心。在您的应用中检查两件事：

是否正确配置了MongoDB网址(Mongo HQ的网址)？这是因为，第二个错误表明链接本身可能存在问题。

较新版本的rails(3及更高版本)不允许环境块中的config.gem语法。相反，您需要在config/initializers中添加初始化文件。有关这方面的更多信息，请参阅MongoDB Documentation for Rails 3部分。

希望这可以帮助。
