Question

I have a Rails app that is using Carrierwave for file uploads. It has been working fine but I want to start using Amazon S3 for my image storage. I am getting this error:

Answer 1

OK, I'm an idiot. :)

At some point, I don't know where, I added a fog.rb file with my CarrierWave configuration to the lib/carrierwave/storage directory. I got desperate, paid for a Railscasts subscription so I could watch episode #383 (http://railscasts.com/episodes/383-uploading-to-amazon-s3?autoplay=true) and at 3:02 I found the error of my ways. The Carrierwave configuration needed to be placed in config/initializers/carrierwave.rb.

I don't know where I got this other location but once I moved the config to the proper location, everything is good.

Answer 2

I just ran into the same problem, and people must be aware that any typo in the config file : "config/initializers/carrierwave.rb", leads to that error.
