Capistrano doesn't install

Question

Whenever I try to run cap production deploy it fails at the following command

[ebbf9fde] Command: cd /var/www/apps/my_app/releases/20150803171251 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/my_app/shared/bundle --without development test --deployment --quiet
DEBUG [ebbf9fde]    /usr/local/rvm/scripts/set: line 19: exec: bundle: not found

I have a added a user 'deploy' to do this deployment, the ouput of rvm list is

$ rvm list

rvm rubies

=* ruby-2.2.2 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

Further running gem list the output is

$ gem list

My Capfile contents are

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

Finally my deploy.rb contains the following data.

after "deploy:finished", "deploy_prepare:create_vhost"

I am getting the following error

Answer 1

Just try gem install bundler on the server once to install bundler into the rvm gemset, as its not in the list of your gem list.

In general try to ensure that the bundle command runs when you log into your server via ssh. Capistrano doesn't do magic, it just logs in via ssh and issues commands. You can always see what commands capistrano issues, like in your example cd /var/www/apps/oxygen/releases/20150803172155 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/oxygen/shared/bundle --without development test --deployment --quiet and try them yourself when something fails.
