I have a rake task that works fine when i run it from the command line from within the app's directory, but when cron runs it it outputs the following error:
/var/lib/gems/2.6.0/gems/bundler-1.17.3/lib/bundler/spec_set.rb:91:in `block in materialize': Could not find spring-2.1.0 in any of the sources (Bundler::GemNotFound)

from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
this is the cronjob:
*/15 * * * * cd /var/www/myapp && /usr/local/bin/bundle exec /usr/local/bin/rake myapp:heartbeat RAILS_ENV=production > /var/www/myapp/log/heartbeat.log 2>&1
the cronjob was working in the past but i recently upgraded ruby to 2.6 and i guess something got messed up in the process.
if i run the following from outside of the app folder i get:
$ bundle show spring
Could not locate Gemfile or .bundle/ directory
but from inside the app folder i get:
$ bundle show spring
/var/www/myapp/vendor/cache/ruby/2.6.0/gems/spring-2.1.0
but considering the cronjob first cds into the app folder this shouldn't be a problem I guess.. Any idea what's going on and how to fix it?

So finally managed to make it work, i set the env variables in the crontab and removed the full paths from the job's command and it finally worked, here's how the working version worked:
/etc/crontab
SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOME=/root
*/15 * * * * root cd /var/www/myapp/ && bundle exec rake myapp:heartbeat RAILS_ENV=production > /var/www/myapp/log/heartbeat.log 2>&1
