( rails 4.1.2 , OS X 10.9.4) Not as expected when I type "rails console" and "rails generate devise:views"

When running " rails console" in the terminal, I got:

/Users/mac/.rvm/gems/ruby-2.1.2/gems/devise-3.3.0/lib/devise/models.rb:88:in const_get': uninitialized constant Devise::Models::ProfileName (NameError) from /Users/mac/.rvm/gems/ruby-2.1.2/gems/devise-3.3.0/lib/devise/models.rb:88:inblock (2 levels) in devise' ...........

And I also got the same error when running "rails generate devise:views ".

What does the error mean ?

Thank you !

Just to make sure the foundations are covered:

1) you have gem 'devise' in your gemfile?

2) did you run bundle install successfully?

3) did you run rails generate devise:install successfully?

Thank you Maciej ! I have <strong> gem 'devise' </strong> in my gem file. I ran<strong> bundle install </strong> successfully but the third one failed.

The error message is the same as before :

/Users/mac/.rvm/gems/ruby-2.1.2/gems/devise-3.3.0/lib/devise/models.rb:88:in const_get': uninitialized constant Devise::Models::ProfileName (NameError) from /Users/mac/.rvm/gems/ruby-2.1.2/gems/devise-3.3.0/lib/devise/models.rb:88:inblock (2 levels) in devise' from /Users/mac/.rvm/gems/ruby-2.1.2/gems/devise-3.3.0/lib/devise/models.rb:87:in `each'

Do you know how I can fix the problem ? Thank you !
