Set ruby path for run model function using whenever gem in rails

Question

In my rails application, i want to run model function using whenever gem. My schedule.rb file like,

set :environment, 'development'
set :output, "#{path}/log/cron.log"
set :job_template, "bash -l -c ':job'"
job_type :runner,  "cd :path && bin/rails runner -e :environment ':task' :output"

every 2.minutes do
  runner "Book.jobrun"
end

every 2.minutes do
    command "echo 'rink4'"
end

And book.rb model like,

self.jobrun
  Rails.logger.info "cronjob is running"
end

But when i run cronjob, in cron.log file showing,

bin/rails:3: undefined method `require_relative' for main:Object (NoMethodError)

How i need to set ruby path or rails path?

Try running which ruby from cron. Is it as you expect? If not, cron is likly defaulting to system Ruby which in your case is probably version 1.8.7 and doesn't have the require_relative function.

Check which ruby executble you're using with which ruby . And use this in the shebang at the top of your bin/rails. for instance

bin/rails

#!/Users/<username>/.rvm/rubies/ruby-2.2.4/bin/ruby.
