应用程序正在Web服务器上正常运行，我尝试在本地运行它，我收到这些错误。 知道问题可能是什么吗？我是Ruby的新手，所以如果这是一个简单的问题，请原谅我

我不知道这是否有用，但我也得到以下警告
弃用警告：您在供应商/插件中拥有Rails 2.3风格的插件！在Rails 4.0中将删除对这些插件的支持。移出它们并将它们捆绑在Gemfile中，或者将它们作为lib / myplugin / *和config / initializers / myplugin.rb折叠到您的应用程序中。有关详细信息，请参阅发行说明：http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released。 （从... / appname / Rakefile：7调用）
