I've read this post Whenever errors and tried to implement the recommendations to no avail. I'm still receiving '/bin/bash: bundle: command not found' error.
On Amazon EC2.

tail -f log/cron_log.log
/bin/bash: bundle: command not found
When I copy the command out of crontab and run it directly, everything works fine (cd /srv/www/myapp/releases/20141022032959 && RAILS_ENV=development bundle exec rake calculate:calculate --silent >> log/cron_log.log 2>&1). It's the prepending of /bin/bash that's messing this up.
How do I get schedule.rb / whenever gem to recognize correct PATH.
Forget about PATH settings in cron files. Setting the PATH does not work.
Set the path to bundle explicitly in your config/schedule.rb
set :bundle_command, "/usr/local/bin/bundle exec"
Edit: exec added so that task can run
If none of the above solution works this did it for me without any additional setup
rvm cron setup
This will include all the right paths for gems so you do this on your machine and you are good to go.
If using rbenv, the path is "/home/YOUR_USER/.rbenv/shims/bundle", so you shoud write at the top of schedule.rb..:
set :bundle_command, "/home/YOUR_USER/.rbenv/shims/bundle exec"

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 a simple rails app with the gem whenever. And there's a module:
module Module1
class << self
def say_hi
puts "hi123"
end
end
end
When I setup whenever, it adds this to cron:
* * * * * /bin/bash -l -c 'cd /home/user123/my_app && bundle exec script/runner -e production '\''Module1.say_hi'\'''
It doesn't work. This command when I'm running it directly in the terminal returns:
/bin/bash: bundle: command not found
Then I try this:
cd /home/user123/my_app && bundle exec script/runner -e production 'Module1.say_hi'
And now an error is:
bundler: command not found: script/runner
However, my rails application is working well; bundle and other stuff are installed.
You can also ensure your PATH ends up in the crontab, by putting the following at the top of the schedule.rb file:
env :PATH, ENV['PATH']
chek this
If above solution don't work for you, try:
env :GEM_PATH, ENV['GEM_PATH']
I am trying to make a simple cron job running this task:
Here is my schedule.rb:
set :environment, "staging"
set :path, "/var/www/my_app/current"
every 2.minutes do
# specify the task name as a string
rake 'cron_test'
end
Here is the task:
task :cron_test => :environment do
out_file=File.new("cron_test.txt", "w")
out_file.puts(Time.now.to_s)
out_file.close
end
I tried to do what is advised on this page but nothing works:
Cron job not working in Whenever gem

Any ideas?
Thanks
What happens when you manually run the command from crontab on the console? Try to run in. See if there are any errors.
/bin/bash -l -c 'cd /var/www/my_app/current && RAILS_ENV=staging bundle exec rake cron_test'
Might be something with local or cron environment. Also logs would be great, capturing any running errors. You can set output log to capture any problems with crontab running the command.
set :output, '/path/to/file.log'
for you example:
set :output, '/var/log/my_app.cron.log'
set :environment, "staging"
set :path, "/var/www/my_app/current"
every 2.minutes do
# specify the task name as a string
rake 'cron_test'
end
Here's the documentation whenever output redirection
Thanks it is working now!
When I created the /var/log/staging_cron.log I read this:
/bin/bash: bundle: command not found
I added env :PATH, ENV['PATH'] on the first line of my schedule.rb, updated the crontab (whenever --update-crontab) and now my test file is well created and updated.
I had a problem about set crontab Ubuntu 14.04 on DigitalOcean VPS.
Here are my steps:
First, create new crontab: crontab -e
Second, i set this command:
This is my crontab which i set it run at 10:26AM everyday:
26 10 * * * /bin/bash -l -c 'cd /var/www/my_app/current && RAILS_ENV=production bundle exec rake check:user >> log/cron_log.log'
Third, i checked crontab as crontab -l
Finally, i restart crontab as sudo service cron restart
But it didn't run anyway (i waited for 10:24 until 10:30), and i copied this command and ran it in my console, it worked very well.
So, i didn't understand why it didn't run same as crontab. Hope everybody can explain or give me some advises. Thank you very much.
EDIT: I tried to use gem whenever but it didn't run.
set :environment, "production"
env :PATH, ENV['PATH']
env :GEM_PATH, ENV['GEM_PATH']
set :output, {:error => "log/cron_error_log.log", :standard => "log/cron_log.log"}
# Learn more: http://github.com/javan/whenever
every :day, at: '10:26am' do
rake "check:user"
end
And i updated my crontab use whenever as whenever -w
But it don't work.
Update:
#Coderhs: I tried run this command bundle exec whenever --update-crontab RAILS_ENV=production, but it didn't work :(.
This is list my crontab when i use command crontab -l:
# Begin Whenever generated tasks for: RAILS_ENV=production
PATH=/var/www/my_app/shared/bundle/ruby/2.2.0/bin:/usr/local/rvm/gems/ruby-2.2.1/bin:/usr/local/rvm/gems/ruby-2.2.1#global/bin:/usr/local/rvm/rubies/ruby-2.2.1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/rvm/bin
GEM_PATH=""
26 10 * * * /bin/bash -l -c 'cd /var/www/my_app/releases/20150710024713 && RAILS_ENV=production bundle exec rake user:check --silent >> log/cron_log.log 2>> log/cron_error_log.log'
# End Whenever generated tasks for: RAILS_ENV=production
It still didn't run.
UPDATE:
The problem was solved. Because in my local TIME was different with SERVER TIME.
So, i had just set SERVER TIME same as my LOCAL TIME. Thank you everybody supported me.
Like previously mentioned, I would use whenever gem.
Make sure you run whenever -w again after each capistrano deploy so its looking for the correct release directory.
Make sure you run whenever -w as the same user that your application is running as. Don't use root unless your app is running as root, which it shouldn't be.
Also, you should have your log dir set as a shared directory in Capistrano deploy config. Something like this in config/deploy.rb :
set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'pids', 'public/uploads', 'public/temp')
Also run the 'date' command in your terminal and see what the time there is. It might not be your local time, so the cron could work but at a totally different time than when you are expecting.
The issue is probably because the user which runs the cron, can't access the ruby command 'bundle'. You will have to use the full bath to the bundle executable file in the crontab.
The better solution for this problem would be to use the whenever gem https://github.com/javan/whenever
It would manage all the stuff related to crontab, to avoid issues like this.
schedule.rb for whenever
set :environment, "production"
set :output, {:error => "log/cron_error_log.log", :standard => "log/cron_log.log"}
env :PATH, ENV['PATH']
env :GEM_PATH, ENV['GEM_PATH']
# Learn more: github.com/javan/whenever
every :day, at: '10:26am' do
rake "check:user"
end
don't forget to run.
bundle exec whenever --update-crontab RAILS_ENV=production
after you set the shedule.rb
I am trying to use whenever to execute a rake task onces a day. Im getting this error
/bin/bash: bundle: command not found

Here is my crontab
# Begin Whenever generated tasks for: /home/af/www/app/releases/20120216172204/config/schedule.rb

# End Whenever generated tasks for: /home/af/www/app/releases/20120216172204/config/schedule.rb
I'm at a loss as to why it isn't working. If I run the command:
cd /home/af/www/app/releases/20120216172204 && rvm 1.9.1-p180; RAILS_ENV=production /home/af/.rvm/gems/ruby-1.9.2-p180/bin/bundle exec rake daily:stats --silent >> /home/af/www/app/releases/20120216172204/log/cron.log 2>&1
It works fine, not sure whats going on here.
You can also ensure your PATH ends up in the crontab, by putting the following at the top of the schedule.rb file:
env :PATH, ENV['PATH']
https://groups.google.com/forum/#!msg/whenever-gem/yRLt3f2jrfU/Exu3xfCo8DAJ
If above solution don't work for you, try:
env :GEM_PATH, ENV['GEM_PATH']
In my case I just ran :
rvm env --path -- ruby-version[#gemset-name]
Referring to cron job setup doc
Added new source line to the command for ruby path
before bundle command in the crontab -e
source /usr/local/rvm/environments/ruby-1.9.3-p392;
Now the commands like as below:
Before:
0 4 * * * cd /home/current && bundle exec rake my_rake RAILS_ENV=production
After:
0 4 * * * cd /home/current && source /usr/local/rvm/environments/ruby-1.9.3-p392; bundle exec rake my_rake RAILS_ENV=production
Cheers!!!
After so many try outs the following seems to work
Type the following from terminal
Type crontab -e
This opens the crontab for editing. You will see two lines as below:
# cron clears out environment variables, but Rubber.root/script/rubber uses
# "rvm do default" to run, so no longer any need to setup ruby env vars here,
# all we need is PATH
PATH=/<path to bundle>/bundle/ruby/1.9.1/bin:/usr/local/rvm/gems
AND
# Begin Whenever generated tasks for: /mnt/wamjoke-production/releases/20120912$
PATH=/<path to bundle>/shared/bundle/ruby/1.9.1/bin:/usr/local/rvm/gems
Comment out both lines beginning with PATH.
Do the above step whenever you run "bundle exec whenever" command. And it works.
No idea why PATH is misleading the environment.
I hate this problem - I've spent hours trying to solve it too.
What works for me is to add
RAILS_ENV=production; source /usr/local/rvm/scripts/rvm;
before the bundle command.
Forget about PATH settings in cron files. Setting the PATH does not work.
Set the path to bundle explicitly in your config/schedule.rb
set :bundle_command, "/usr/local/bin/bundle"
You can try below solution which I found while googling and that works for me finally....hope that should work with you.
I implemented and tested the same on production make sure that to change environment accordingly -
set :output, "{your path on the server}/log/cron_log.log"
set :environment, :production
env :PATH, ENV['PATH']
job_type :rbenv_rake, %q!eval "$(rbenv init -)"; cd :path && :environment_variable=:environment bundle exec rake :task --silent :output!
Best luck, This issue occurred after 3 years as I was using before just simple what given on the gem documentation on production.
I'm using Ruby 2.x and Rails 4.2 with whenever 0.9.4 latest version. It should work with earlier version as well, if the nature of the issue is same.
thank you.
I think you should try explicitly setting the GEM_HOME and GEM_PATH environment variables in your crontab. You could also try running something like gem list --local or gem environment through cron and checking the output.
I played around with this all afternoon and couldn't find a better solution. Here is what I have come up with
bundle install --binstubs
and then run
bin/rake daily:stats
By executing a command that way: /bin/bash -l -c
You are launching a bash command as a login shell which is going to source (execute) /etc/profile bash file as a setup file. By doing so, if you check this file, it might have bash command lines that erase your previous $PATH which you do not want to since it contains your path to your bundle and all your other commands in the first place.
To fix this issue you just have to remove the lines related to set up the $PATH variable in your /etc/profile file.
This is a ENV['PATH'] not set issue. The most elegant way to fix this is to append the rvm related scripts to the path right after the install. Add the following lines to beginning of .bashrc ( beginning and not end as when .bashrc is accessed by a non-interactive shell, the line [ -z "$PS1" ] && return throws error and the subsequent lines are not executed.
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
and not try to explicitly set PATH and sully environment variables.
For those using rbenv you can use the included shim /home/username/.rbenv/shims/bundle
0 0 * * * /bin/bash -l -c 'cd /home/af/www/app/releases/20120216172204 && RAILS_ENV=production /home/af/.rbenv/shims/bundle exec rake daily:stats --silent >> /home/af/www/app/releases/20120216172204/log/cron.log 2>&1'
in 2021, I found a basic solution, just add on top of schedule.rb
env :PATH, ENV['PATH']
set :output, "log/cron_log.log"
set :runner_command, "rails runner"
from:
https://github.com/javan/whenever/issues/665
I solved this problem by printing out my environmental variables
printenv
finding the ones that look related to Rails. One was a path to gems, the other was GEM_HOME and prepending the command in cron with these two:
PATH=$PATH:/home/petr/gems/bin GEM_HOME=/home/petr/gems program_executable
Also in 2021, adding this in schedule.rb worked for me:
set :job_template, "bash -l -c 'PATH=#{ENV['PATH']} && :job'"
All jobs are by default run with bash -l -c 'command...' (https://github.com/javan/whenever)
So I made bash include ENV['PATH'] in PATH at the beginning and now rails are called from the proper rbenv.
For modern fix, add this line in capistrano deploy.rb,
set :whenever_command, "bundle exec whenever"
[root#smbserver current]# crontab -e
02 22 * * 1-5 /bin/bash -l -c /shell/day.sh
