I recently changed from rvm to asdf.
Since then, I can't get cronjobs to run.
crontab -l
* * * * * /bin/bash -l -c 'cd /var/www/jobs/code && RAILS_ENV=production bundle exec rake cron_test' >> /tmp/cron_test_output 2>&1 /tmp/cron_error
gives me /tmp/cron_error: bundle: command not found. There is no output to stderr.
gem install bundler has not worked for the jobs user.
Not sure where to install bundler to make this work.
The rake tasks work when run independently. The cronjobs that are not rake tasks run. Cron is working.
Edit:
While the cronjobs were working before, they obviously can't now find the location of bundler. By changing bundle exec to the full path /home/jobs/.asdf/shims/bundler exec, I have managed to get this to work.
I have been using the whenever gem to create cron jobs for rake tasks. Turns out the easiest way to get around this problem is to make sure that the environment path is included in the whenever generated crontab.
within config/schedule.rb for the whenever gem, I added the following:
env :PATH, ENV['PATH']
and now everything is working as the cron job can now find the bundler.
Based on this issue from the whenever gem.
And this one too.

I have this script that should be running from the /~ directory:
#!/bin/bash
APP=/root/apps/monitoring
cd $APP
git pull
rake assets:precompile RAILS_ENV=production
touch $APP/tmp/restart.txt
As you can see, it pulls new commits and updates the assets and restarts Apache. The problem is when it runs the line rake assets:precompile RAILS_ENV=production, It says:
Could not find proper version of rake (12.1.0) in any of the sources
Run `bundle install` to install missing gems.
Which is strange because I am supposed to be inside the app's folder (/root/apps/monitoring) when this command is executed. What I am doing wrong?
You may need to load rvm in the script (https://rvm.io/workflow/scripting) and may be select proper ruby/gemset.
Also you can consider using wrapper for bundle created with rvm wrapper
Please try
#!/bin/bash
APP=/root/apps/monitoring
cd $APP
git pull
bundle exec rake assets:precompile RAILS_ENV=production
touch $APP/tmp/restart.txt
With bundle exec it should work.
I run rake tasks using bash script wrappers. The trick is to use the source command to load in the rvm environment after the task is started
example.sh
#!/bin/bash
# change the directory
cd /home/ubuntu/GSeries
# load rvm ruby
source /home/ubuntu/.rvm/environments/ruby-2.4.2#mygemset
bundle exec rake db:prune_logs RAILS_ENV="production" &>> /home/ubuntu/GSeries/log/prune_logs.log
I'm trying to run rake task with cron on Ubuntu with rvm
My crontab -l
* * * * * cd /media/sf_visa-tracker/ && /home/ruslan/.rvm/gems/ruby-2.1.0/bin/rake parse RAILS_ENV=production >> /var/log/visa-parse.log 2>&1
which rake says
/home/ruslan/.rvm/gems/ruby-2.1.0/bin/rake
And I keep getting this error in my log (/var/log/visa-parse.log)
/usr/bin/env: ruby_executable_hooks: No such file or directory
Also, if I run cd /media/sf_visa-tracker/ && /home/ruslan/.rvm/gems/ruby-2.1.0/bin/rake parse RAILS_ENV=production from my terminal, rake task works.
Pls help ;)
The simplest way to use rvm with cron is to use rvm's wrappers. Your shell sets up a whole bunch of rvm-related environment when it starts, and that's missing from your cron job. The wrappers are versions of the Ruby-related commands that take care of this for you.
In this case, if you have rvm installed to /usr/local, your cron job should look something like this:
* * * * * cd /media/sf_visa-tracker/ && /usr/local/rvm/wrappers/ruby-2.1.0/bin/rake parse RAILS_ENV=production >> /var/log/visa-parse.log 2>&1
You could also bundle up your rvm setup into a shell script that loads rvm before invoking rake; there's more details of both approaches in rvm's documentation on working with cron.
I struggled to get something that worked and seemed clean. Here's what I ended up doing in case it helps.
crontab
0 5 * * * /home/deploy/apps/myproject/shared/cron/daily_updates.sh
I put the script in myproject/shared since I'm using Capistrano and that seemed like a good place for things that would persist between releases.
shared/cron/daily_updates.sh
#!/usr/bin/env bash
# You will need to update this as you bump ruby versions
source /home/deploy/.rvm/environments/ruby-2.3.1#myproject
# Since I had a separate place for Rails specific environment variables (e.g. secrets, app keys)
# you should set the permissions on that file to be owner read/write only
source /home/deploy/.rails_env
cd /home/deploy/apps/myproject/current
rake RAILS_ENV=production daily_update:send_updates 2>&1
I am using RVM environment. RUby version : 2.1.2 rails : 4.1.1
schedule.rb :
every 1.minute do
runner "note.send_mail"
end
I used whenever --update-crontab to update the cron tab.
when I check the jobs using crontab -l it shows up as below with no proper time set up.
and the cron job does not work.
* * * * * /bin/bash -l -c 'cd /Desktop/folder1/blog2 && bin/rails runner -e production '\''note.send_mail'\'''
Can some one help me out fix this. Thanks!
Go to your ~/.rvmrc file and add the following:
rvm_trust_rvmrcs_flag=1
Then whenever --update-crontab again. According to the README of whenever:
If your production environment uses RVM (Ruby Version Manager) you will run into a gotcha that causes your cron jobs to hang. This is not directly related to Whenever, and can be tricky to debug. Your .rvmrc files must be trusted or else the cron jobs will hang waiting for the file to be trusted. A solution is to disable the prompt by adding this line to your user rvm file in ~/.rvmrc
rvm_trust_rvmrcs_flag=1
This tells rvm to trust all rvmrc files.
If that doesn't work for you, try other solutions mentioned in this page: RVM-Notes.
You could define a custom runner that loads rvm on the command line, like
job_type :runner_with_rvm, 'source /etc/profile.d/rvm.sh; cd :path;rvm 2.0#gemset do bundle exec script/rails runner -e :environment ':task' :output'
every 1.minute do
runner_with_rvm "Note.send_email"
end
Replace 2.0#gemset with your desired ruby version and gemset.
Could be that /etc/profile.d/rvm.sh is something else in your environment too.
I would like my cron job, which calls a rake task, to use the gems installed in either [rails_app]/vendor/bundle or [rails_app]/vendor/cache. Currently, my system gems are out-of-date, but I cannot update them for various reasons beyond my control.
I tried using bundle exec, but this does not seem to work. The error I get is
usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.0.18/lib/bundler/spec_set.rb:88:in 'materialize': Could not find rake-0.9.2.2 in any of the sources (Bundler::GemNotFound)
I believe this is because my system's rake is out-of-date. I tried using bundle exec rake _0.9.2.2_ [my_task] in the cron job, but the same error appeared
I tried the whenever gem; this produced the exact error.
So I guess I have two questions:
How do I make cron use the correct rake version? And
How do I point it to gems already in vendor/bundle or vendor/cache?
Note that the site works when deployed in Phusion Passenger.
While hunting a solution for the same problem I found this Thread with several tips.
the quick & easy way for me was to just run the cron command as login shell - like this:
* * * * * /bin/bash -l -c 'bundle exec rake _0.9.2.2_ [my_task]' 2>&1
the ending 2>&1 is just to be sure to receive errors in cron log. also see man bash for further info!

Got the following rake task in my app user's crontab which is meant to pull records into a database table every 15 min:
*/15 * * * * app_user cd /var/www/apps/my_app/current/ && rake thing:do_stuff RAILS_ENV=production
I can see that the cron daemon is running this task in the cron log, but the database table it's supposed to pull records into doesn't change. This task is working without error when I run it manually in the /var/www/apps/my_app/current directory, and pulls records into the table as I expect it to.
I reset the PATH variable in the crontab to reflect using REE, thinking maybe the default path wouldn't jive with /opt/ruby-enterprise...
How do I get this rake task to actually run with cron?
0,15,30,45 * * * * /bin/bash -l -c 'cd /var/www/apps/my_app/current && RAILS_ENV=production bundle exec rake thing:do_stuff --silent'
Try to use full path to rake binary (run in console which rake and replace rake with full path).
For example, if which rake returns the following path:
/Users/bob/.rvm/gems/ruby-1.9.3-p194/bin/rake
You should use the following command to run the rake task:
/Users/bob/.rvm/bin/rvm all do bundle exec rake allocator:snapshot
and I prefer whenever gem for cron jobs in ruby
How to detect if task failed in cron? On fail cron tries to send email. So you can configure postfix to use your smtp settings (from google for example), and add file ~/.forward containing only your email to home directory of user who is running that cronjob in your system.
