Loading the correct gem version error LoadError: cannot load such file -- capistrano/rails

I am trying to run a capistrano update: cap production deploy

But I get the error: cap aborted! LoadError: cannot load such file -- capistrano/rails /home/deploy/apps/my-web-app/releases/20151214160634/Capfile:7:inrequire' /home/deploy/apps/my-web-app/releases/20151214160634/Capfile:7:in <top (required)>'

Here it is with --trace

$cap production deploy --trace

I believe there is an issue with the version of capistrano, so I uninstalled it and tried it with '2.15' but that version gives the same error.

Capistrano is defined in my Gemfile like this:

...
group :development do
    gem 'capistrano',         require: false
    gem 'capistrano-rvm',     require: false
    gem 'capistrano-rails',   require: false
    gem 'capistrano-bundler', require: false
    gem 'capistrano3-puma',   require: false
...

EDIT 1

bundle exec cap production deploy

gives:

/home/deploy/.rvm/gems/ruby-2.1.7/gems/bundler-1.10.6/lib/bundler/rubygems_integration.rb:292:in `block in replace_gem': capistrano is not part of the bundle. Add it to Gemfile. (Gem::LoadError)
from /home/deploy/apps/my-web-app/shared/bundle/ruby/2.1.0/bin/cap:22:in `<main>'

EDIT 2

I moved the capistrano lines in the gemfile outside of the group and ran rvmsudo bundle install.

Now bundle exec cap production deploy gives:

bundle exec cap production deploy --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
cap aborted!
NameError: undefined local variable or method `config' for main:Object

Use bundle exec cap production deploy to ensure that the gems declared in your Gemfile are being used.
