Mina deploy can't find bundle

Question

Trying Mina for the first time with a Ruby on Rails app, but on deploy as root user, it seems that it doesn't see Bundler.

I'm using Digital Ocean as the remote server.

If I SSH into the remote server as the same root user, bundle runs fine. Git cloning works, the file structure is set up through :setup, and all else seems fine.

The deploy is using 'root' user, which yes, I will ultimately change to another user.

Here is my deploy.rb

require 'mina/bundler'
require 'mina/rails'
require 'mina/git'

set :domain, 'example.com'
set :deploy_to, '/var/www/example.com'
set :repository, 'git@git.example.co:example.git'
set :branch, 'digital_ocean'
set :shared_paths, ['log']

# Optional settings:
set :user, 'root'    # Username in the server to SSH to.

task :setup => :environment do
  ... *standard code removed*
end

desc "Deploys the current version to the server."
task :deploy => :environment do
  to :before_hook do
    # Put things to run locally before ssh
  end
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    to :launch do
      queue "mkdir -p #{deploy_to}/#{current_path}/tmp/"
      queue "touch #{deploy_to}/#{current_path}/tmp/restart.txt"
    end
  end
end

And this is the -- verbose output from 'mina deploy --verbose':

   $ touch "deploy.lock"

Assuming bundler is installed on your server you have to specify the full path to the bundle command if it cannot be found in path.

set :bundle_bin, "/path/to/bundle"
