Gemfile not found when running Cron job with Capistrano 3 and whenever gem

Question

My cron job works fine on my local machine after running whenever -w, after deploy to my VPS, I get this error, release 20150415044915 doesn't exist. any idea?

I looked at my crontab -e, the path also looks fine where 20150502114703 is the correct release:

0 1 * * 1 /bin/bash -l -c 'cd /home/hey_production/releases/20150502114703 && bin/rails runner ....

Error Log:

The `Gemfile` will be found under the `current` folder of the release path. i.e. at `/home/hey_production/releases/20150415044915/current/Gemfile` - not `/home/hey_production/releases/20150415044915/Gemfile`. — Prakash Murthy, May 02 '15 at 13:14
It should point to `/home/hey_production/current/Gemfile`. Release *20150415044915* might get cleaned up in the future. — Nitish Parkar, May 02 '15 at 16:31
@PrakashMurthy `/home/hey_production/current` points to the release `/home/hey_production/releases/20150415044915`. Not the other way around. Or am i mistaken? The `/home/hey_production/releases/20150415044915` folder would not have any `current` directory because its a release. — Saad Masood, May 04 '15 at 14:05

Basically the environment variable is missing that tells the cron where to look for a Gemfile. so you need to add that variable in your environment at the time when cron tries to run this. You can do that in Your schedule.rb:

env BUNDLE_GEMFILE, ENV["/home/hey_production/current/Gemfile"]

or directly inside crontab file with the command crontab -e(before the cron entries):

BUNDLE_GEMFILE="/home/hey_production/current/Gemfile"

Hope it helps.

EDIT Forgot the symbol above in schedule.rb

The line in schedule.rb should be like this.

env :BUNDLE_GEMFILE, ENV["/#{path}/Gemfile"]

or

env :BUNDLE_GEMFILE, ENV["/home/hey_production/current/Gemfile"]

Thanks, insert BUNDLE_GEMFILE="/home/hey_production/current/Gemfile" into crontab -e works, and env BUNDLE_GEMFILE, ENV["/home/hey_production/current/Gemfile"] raise BUNDLE_GEMFILE undefined when I deploy using Capistrano, any idea? – user1883793 May 05 '15 at 22:37
Yes. I'm not sure of the syntax in the schedule file. I will get back to you soon with the correct syntax. – Saad Masood May 05 '15 at 22:39

As a follow up on previous answer, set the env variable in whenever inside schedule.rb before the schedule blocks like:

def production?
  @environment == 'production'
end

set :output, {:error => '/home/current/log/cron_error.log', :standard => '/home/current/log/cron.log'}

every 2.hour, roles: [:utility] do
  runner "/home/current/lib/cron_jobs/launch_pending_emails.rb"
end

and inside your deploy.rb environment specific file ie: staging.rb set the env:

set :whenever_roles, [:utility]
set :whenever_environment, defer { stage }
set(:whenever_command) { "STAGE=#{stage} bundle exec whenever" }
require 'whenever/capistrano'
