Please read: With regards to Gemfiles and Devise

Across the board, Devise changed between 2.0 and 2.1 so that things that were methods are now in migrations. The fix, while frustrating, is simple:

Change gemfile from

gem 'devise'

to

gem 'devise', '< 2.1'

And that should give you Devise 2.0.5, which allows migrations to run clean. To verify this, you can

rake db:drop
rake db:create
rake db:migrate
rake db:seed

(or rake db:reset, but I like to do each step to ensure no faiilures)

ALSO, there are issues with Paperclip. Please change that line to

gem “paperclip”, ”~> 2.7”

to get Seeds to work.
