Capistrano doesn't install - ruby-on-rails

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

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.

Answer 2

Be sure you have bundler installed in the correct gemset.
I got this error and was scratching my head because bundler was installed in the default gemset, but it was not in the one I was using for my rails application.
When I realized it I was like, "doh!"
Just thought I would post this here, hopefully it will help someone else.

Answer 3

This didnt work for me, gem install bundler
I realized I didn't set my deploy.rb file correctly.
So because I am using RVM, I checked the rvm list for the ruby version
jruby-1.7.19 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
then config my deploy.rb file to set :rvm_ruby_version, 'ruby-2.2.1'

Answer 4

On your server
rvm 2.2.2#gemset-name do gem install bundler
