Rails app moved to production server gives "dump format error for symbol" error
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)
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!
Had the same problem. Try removing your [app]/tmp dir. It seems to be trying to unmarshal some borked files.
Change an asset from new.js to new.js.coffee and received this error when trying to render a view which was trying to render new.js:
ActionView::Template::Error (dump format error for symbol(0x6d))
I figured it was something related to the tmp files (thanks to the comments in this thread). I ran:
bundle exec rake tmp:clear
And I was good to go!
The problem here was that I inserted "haml-rails" under the :assets pipeline, so it was not able to find HAML on the production environment.
By the way I fixed it by moving haml-rails out from the assets scope.
I ran into the same issue when I removed a bunch of unused .coffee files from my assets.
I resolved the issue by running:
bundle exec rake assets:precompile RAILS_ENV=<environment>
And then restarting the server.
This doesn't look like a passenger error, my guess would be a problem with your HAML. Try removing 8, 9, and 10, and see if it renders. If it does, that will let you narrow down the problem.
I had the same problem, and the fix was to run git clean -dfx
