Bundle install doesnt install gem in Gemfile - ruby-on-rails

Question

I am typing the following command:
rake -RAILS_ENV=production db:schema:load
In the home directory of my rails app on my production server and I get the following error message:
rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.)
This is strange because I know that pg is in my Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.8'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :development, :production do
gem 'pg'
gem 'devise'
gem 'haml-rails'
gem 'paperclip'
gem 'will_paginate'
end
group :development do
gem 'capistrano'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
And when I run bundle install from that directory I get the following output (pg is not on it.):

- rvm 1.16.5
Can anyone offer an explanation as to why bundle install is not installing all the gems listed in my Gemfile?

Answer 1

Through some detective work I found out the following factors contributed to my problem:
1) I was developing on a Windows machine that installed the windows-specific version of the gem pg: (0.14.0-x86-mingw32).
2) This was then added to my Gemfile.lock and consequently my repo that capistrano then used to install my app on a Debian box with; pg was listed as a dependency, only.
3) capistrano was running bundler with the "--deployment" flag, which requires your Gemfile.lock to be up-to-date and accurate.
How I resolved the problem was removed the "--deployment" flag from capistrano with the following variable definition in deploy.rb:
set :bundle_flags, "--quiet"
require 'bundler/capistrano'
And ran the cap deploy:update again.
Still working on a way to have the Gemfile.lock reflect that pg should be installed on the production environment, while pg should be installed on the development machine so I can include the --deployment option back into the deployment task.

Answer 2

You have to use bundler to execute rake:
bundle exec rake db:schema:load RAILS_ENV=production

Answer 3

For the database.yml
it should be
development:
adapter: postgresql
encoding: utf8
database: xxx
host: localhost
username: username
password: pw
the adapter for postgresql is postgresql
And for the gem file, make sure pg is there
and you don't need a block if it exist in both development and production
