Description
I added these lines to deploy.rb as instructed.
set :whenever_command, "bundle exec whenever"
require "bundler/capistrano"
require "whenever/capistrano"
I got the following error when I tried to run cap deploy. Any ideas? My schedule.rb is commented out so it is not that. My ruby is 2.1.3 and rails is 4.1.8. This happens when it executes `whenever:update_crontab'.
** [out :: mydomain] /path/to/app/shared/bundle/ruby/2.1.0/gems/whenever-0.9.4/lib/whenever/command_line.rb:77:in `write_crontab':
** [out :: mydomain] undefined method `zero?' for nil:NilClass (NoMethodError)

Research direction
Start in whenever/command_line.rb at the reported write_crontab failure and trace the whenever:update_crontab path when the remote user has no crontab. Reproduce the deployment scenario with an empty crontab, then verify the command completes successfully and preserves the expected schedule output.
