Rails app moved to production server gives "dump format error for symbol" error
deployment, passenger, ruby, ruby-on-rails, ruby-on-rails-3
Solution
Had the same problem. Try removing your [app]/tmp dir. It seems to be trying to unmarshal some borked files.
Problem
I've just moved my rails app from the development to deployment server. I've installed passenger, but I wanted to try with `rails s` to make sure all was running fine (this is the first time I develop and deploy a rails application). Specs are: Ruby 1.9.3 with RVM, mod_passenger, Rails 3.2.3. All installed correctly and I've also enabled the Apache module. By the way something is going wrong (passenger keeps sayng "Error message: Unknown key: class".) Running `rails s` is giving a weird error listed above `dump format error for symbol(0x45)` ``` Processing by Devise::SessionsController#new as HTML Rendered devise/_links.haml (2.2ms) Rendered devise/sessions/new.html.haml within layouts/application (11.8ms) Completed 500 Internal Server Error in 110ms ActionView::Template::Error (dump format error for symbol(0x45)): 8: / HTML5 shim, for IE6-8 support of HTML elements 9: /[if lt IE 9] 10: = javascript_include_tag "http://html5shim.googlecode.com/svn/trunk/html5.js" 11: = stylesheet_link_tag "application", :media => "all" 12: /%link(href="images/favicon.ico" rel="shortcut icon") 13: /%link(href="images/apple-touch-icon.png" rel="apple-touch-icon") 14: /%link(href="images/apple-touch-icon-72x72.png" rel="apple-touch-icon" sizes="72x72") app/views/layouts/application.html.haml:11:in `_app_views_layouts_application_html_haml__3524679841439843142_22055600' ``` What does it mean? Googling it seems a flash[] error but I can't really understand what should I do here. Waiting for some suggestion, thank you!
