cap aborted! Don't know how to build task 'deploy:setup'     

In my Capfile, I have these:

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
require 'capistrano/passenger'

Answer 1

Looks as though you're relying on the standard setup task to be there. You'll need to add it your cap file:

# Capfile
require 'capistrano/setup'

and make sure to run bundle exec cap production deploy:setup .

Your are using cap 3, right?
