bundler rails with user problem

Hello, I have a drop in digitalocean, and I installed ruby on rails through the main panel, I can not use the bundler through upstart or cron, it says that the user does not have the bundler, but when access via ssh do everything normally. ex: bundle exec ....

I do not know what happened, I tried to run

sudo -su root bundle exec .....

or

sudo -su rails bundle exec .....

But it does not, how do I execute the bundler with the same characteristics that I use via ssh?
