Undefined method `extension_whitelist'

I'm trying to set the avatar of a user in a seed file (as per the instructions at carrierwave's github readme):

File.open(Rails.root.join('app', 'assets', 'images', 'Jurgen.png')) do |f|
  user.avatar = f
end

user.save!

I'm getting the following error:

NoMethodError: undefined method `extension_whitelist' for nil:NilClass

Using Rails 5.2.0.beta2.

Also, I found I had to add the carrierwave gem in my Gemfile before the avatari gem because of an uninitialized constant error, similar to #2.

Railtie fails to load causing rails to fail at startup

Rails (5.2.0.beta2) project fails to load because of constant error.

/app/vendor/bundle/ruby/2.4.0/gems/bootsnap-1.1.5/lib/bootsnap/load_path_cache/core_ext/active_support.rb:49:in `block in load_missing_constant': uninitialized constant Avatari::Railtie::Mozaic (NameError)

This occurs because the Mozaic constant isn't required prior to calling the initializer 'avatari.mozaic' block in the Railtie. To get around this I added the mozaic gem to my Gemfile before the avatari gem.

Ideally however, you could add a require statement in the Railtie and maybe prefix the constant with a ::.
