将Rails应用程序从3.2.0升级到rails console后，出现以下错误。
rails server很好。而且，我能够在控制台中执行代码。但是，当我运行browser并在Rendered /home/sarwan/.rvm/gems/ruby-1.9.3-p551@project-name/gems/actionpack-3.2.21/lib/action_dispatch/middleware/templates/rescues/_trace.erb (0.8ms)中打开页面时。它失败并显示以下错误。
SystemStackError（堆栈级别太深）： actionpack（3.2.21）lib / action_dispatch / middleware / reloader.rb：70
