Capistrano Error: '/usr/bin/env ruby : No such file or directory'

Question

When I try to restart unicorn using Capistrano:

$ cap production deploy:restart_unicorn

I got this error:

DEBUG [c65b4a92]  /usr/bin/env:
DEBUG [c65b4a92]  ruby
DEBUG [c65b4a92]  : No such file or directory

My environment:

Mac OSX 10.9.2
Capistrano Version: 3.2.1 (Rake Version: 10.3.1)
rvm 1.25.25 (stable)
ruby 2.1.2p95
Rails 4.1.1
Bundler 1.6.2

My server environment:

Ubuntu 14.04 LTS (GNU/Linux 3.13.0-24-generic x86_64)

My config/deploy.rb:

lock '3.2.1'

set :application, 'my_app'
set :repo_url,    '[email protected]:my_app.git'
set :deploy_to,   '/var/www/my_app'

set :linked_files, %w{.env}
set :linked_dirs, %w{bin log tmp/pids tmp/cache public/system}
set :rvm_ruby_version, '2.1.2'

namespace :deploy do
  desc 'Restart application'
  task :restart_unicorn do
    on roles :app, in: :sequence, wait: 5 do
      execute 'service unicorn upgrade'
    end
  end

  after :publishing, :restart_unicorn
end

My unicorn init script:

#!/bin/sh
set -e
. /etc/environment

TIMEOUT=${TIMEOUT-60}
APP_ROOT=/var/www/my_app/current
PID=$APP_ROOT/tmp/pids/unicorn.pid
CMD="$APP_ROOT/bin/unicorn -D -c $APP_ROOT/config/unicorn.rb -E $RAILS_ENV"
action="$1"
set -u

cd $APP_ROOT || exit 1

sig () {
  test -s "$PID" && kill -$1 `cat $PID`
}

case $action in
restart)
  sig HUP && echo reloaded OK && exit 0
  echo >&2 "Couldn't reload, starting '$CMD' instead"
  $CMD
  ;;
esac

My Gemfile:

# ...
gem 'capistrano', '~> 3.2.0'
gem 'capistrano-bundler', '~> 1.1.2'
gem 'capistrano-rails', '~> 1.1'
gem 'capistrano-rvm'
# ...

My Capfile:

require 'capistrano/setup'
require 'capistrano/deploy'

require 'capistrano/bundler'
require 'capistrano/rvm'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

I've fixed the problem just adding the PATH variable to my unicorn init script:

#!/bin/sh
set -e
. /etc/environment

PATH=/usr/local/rvm/rubies/ruby-2.1.2/bin:$PATH
TIMEOUT=${TIMEOUT-60}
# ...
