Question

Using lubuntu 12.10, ruby 1.9.3p374(not RVM), Gem 1.8.23, and Rails 3.2.11

I’ve just recently installed the Whenever gem to create tasks that will run periodically. I created my task which runs every 1 minute and set it to run using:

whenever --update-crontab myproject --set environment=development

This command puts the following entry in my crontab:

* * * * * /bin/bash -l -c 'cd /home/myuser/projects/myproject && script/rails runner -e development '\''FileImporter.execute'\'' >> /home/myuser/projects/myproject/log/cron_log.log 2>&1'

After waiting for some time I see that in my cron_log.log file spammed with the same exception:

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in 'require: cannot load such file -- bundler/script (LoadError)

However, when I run the following command manually in the terminal everything works just fine:

/bin/bash -l -c 'cd /home/myuser/projects/myproject && script/rails runner -e development '\''FileImporter.execute'\'' >> /home/myuser/projects/myproject/log/cron_log.log 2>&1'

Let me know if any more information is needed, I’m pretty new to the rails/linux world so I may have left some important stuff out.

Found the answer here on a similar question: why #!/usr/bin/env ruby doesn't work in crontab?

Apparently PATH isn’t set when the cron job executing so you have to set it in the crontab.

Running echo $PATH to see what PATH is set to and putting PATH=/my/path/values at the beginning of the crontab file fixes the issue.
