Rails cron 每当 gem 错误时，bundle: command not found

Question

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.

which ruby

/usr/local/bin/ruby

which bundler

/usr/local/bin/bundler

schedule.rb

env :PATH, ENV['PATH']
require File.expand_path('../application', __FILE__)
set :output, "log/cron_log.log"

every 1.minutes do
  rake "calculate:calculate"
end

crontab -e

• • • • • /bin/bash -l -c 'cd /srv/www/myapp/releases/20141022032959 && RAILS_ENV=development bundle exec rake calculate:calculate --silent >> log/cron_log.log 2>&1'

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.

Answer 1

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

Answer 2

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.

Answer 3

如果使用rbenv，路径是“/home/YOUR_USER/.rbenv/shims/bundle”，所以你应该写在schedule.rb..的顶部：

set :bundle_command, "/home/YOUR_USER/.rbenv/shims/bundle exec"
