Your sqlite3
gem is not being loaded in production, because of where you've got it in the Gemfile. Take it out of any groups, or move it to the group :test, :production
group.
Capistrano, Rails "gem is not loaded. Add `gem 'sqlite3'` to your Gemfile"

문제
To start off, I am a beginner when it comes to Rails and Capistrano. My development environment works without any issues and I wanted to push first as a test environment on a local virtual machine with the same setup as my production server.
I chose Capistrano to handle the deployment and setup everything according to the tutorial of the official website.
The specs are:
- ubuntu
- ruby-2.0.0-p247
- rails 4.1.0.beta1
- capistrano 3
- phusion passenger
My Gemfile:
gem 'rails', '4.1.0.beta1'
gem 'rails-i18n', '~> 4.0.0'
group :assets do
# Use SCSS for stylesheets
gem 'sass-rails', '4.0.2'
gem 'uglifier', '>= 1.3.0'
end
gem 'bourbon'
gem 'foundation-rails'
group :development do
gem 'capistrano', '~> 3.0.1'
gem 'net-ssh', '~> 2.7.0'
gem 'capistrano-rails', '~> 1.1.0'
gem 'capistrano-bundler'
gem 'capistrano-rvm'
gem 'capistrano-rbenv', "~> 2.0"
end
group :development, :test do
gem 'sqlite3'
gem 'rspec-rails'
end
group :test, :production do
# gem 'mysql2'
end
gem 'jquery-rails'
My deploy.rb file:
set :application, 'appliname'
set :deploy_user, 'deploy'
set :use_sudo, false
set :repo_url, 'git@server:path/to/project.git'
set :branch, "master"
set :scm, :git
# set :format, :pretty
# set :log_level, :debug
set :pty, true
# setup rvm.
set :rbenv_type, :system
set :rbenv_ruby, 'ruby-2.0.0-p247'
set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec"
set :rbenv_map_bins, %w{rake gem bundle ruby rails}
# files we want symlinking to specific entries in shared.
set :linked_files, %w{config/database.yml config/private_env.yml}
# dirs we want symlinking to shared
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }
set :keep_releases, 5
namespace :deploy do
# make sure we're deploying what we think we're deploying
# only allow a deploy with passing tests to deployed
# before :deploy, "deploy:run_tests"
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Your restart mechanism here, for example:
execute :touch, release_path.join('tmp/restart.txt')
end
end
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
within release_path do
execute :rake, 'cache:clear'
end
end
end
# compile assets locally then rsync
# after 'deploy:symlink:shared', 'deploy:compile_assets'
# after :finishing, 'deploy:cleanup'
end
deploy/test.rb
set :stage, :test
server 'testserver.local', user: fetch(:deploy_user), roles: %w{web app db}
set :deploy_to, '/home/project/public'
set :enable_ssl, false
My database.yml At first I wanted to use MySql even for my test environment, but for the deployment debugging sake, I temporary put sqlite.
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
test: &test
<<: *default
database: db/test.sqlite3
# adapter: mysql2
# encoding: utf8
# reconnect: true
# database: ENV['database']
# pool: 5
# username: ENV['username']
# password: ENV['password']
# host: localhost
production:
<<: *test
And finally the error message after running the following deply command:
cap test deploy

Tasks: TOP => deploy:assets:precompile
(See full trace by running task with --trace)
The deploy has failed with an error: #<SSHKit::Command::Failed: rake stdout: Nothing written
rake stderr: Nothing written
So basically, with either the MySql2 gem or sqlite gem, I have the same kind of error... I am completely lost and have been looking over the web and did multiple tests with no avail.
Obviously I have run on the dev computer 'bundle update' and 'bundle install' when necessary. But I suppose that all these commands are run automatically by Capistrano on deployment.
So if a good soul could help with this it would make me very happy and I might stop losing my hair (or not) :)
If more info is needed, please ask! Thank you

Your sqlite3 gem is not being loaded in production, because of the version mismatch.
so, update you gemfile as gem 'sqlite3', '~> 1.3.13'
it'll work.
Keep it under group :production, :test
It'll be good when you push your code to heroku.
