I get the following error while implementing rake db:migrate
rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.)
I have created two tables in the database using postgresql.
My database.yml is
development:
adapter: postgresql
encoding: unicode
host: localhost
database: shop_development
pool: 5
username: postgres
password:
test:
adapter: postgresql
encoding: unicode
host: localhost
database: shop_test
pool: 5
username: postgres
password:
production:
adapter: postgresql
encoding: unicode
host: localhost
database: shop_production
pool: 5
username: postgres
password:
I have also run the command such as:
C:\Sites\shop>gem install 'pg'
Successfully installed pg-0.14.1-x86-mingw32
1 gem installed
Installing ri documentation for pg-0.14.1-x86-mingw32...
Installing RDoc documentation for pg-0.14.1-x86-mingw32...
but this is still giving me the same error.

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem
is installed.
Please try with this..
sudo apt-get install postgresql postgresql-client postgresql-contriblibpq-dev
Have you run bundle install?
It looks like sqlite3 is currently installed but pg isn't.
If you're moving data from sqlite3 to pg then have a look at this railscast: Migrating to PostgreSQL

I have a rails project, which uses resque workers, with a Gemfile like this:
source 'https://rubygems.org'
gem 'rails', '3.2.5'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
gem 'rest-open-uri'
# 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 'therubyracer' # If using Ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'less-rails-bootstrap'
gem 'devise'
gem 'net-http-digest_auth', '1.2.1'
gem "resque", :require => "resque/server"
gem 'carrierwave'
gem 'kaminari'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
After I do a bundle install and try to start some resque workers with the command rake resque:work QUEUE=checker_queue or bundle exec rake resque:work QUEUE=checker_queue my machine stops responding (to anything). When I observe the system with htop I see that rake creates new processes until both memory and swap space of the machine is full (at which point machine becomes unresponsive).
Any ideas regardind the cause of this strange behaviour?

Maybe there is a bug in app code that schedules resque jobs or maybe there are lots of jobs pending or maybe the problem lies in the task itself. In any case also try to inspect resque status:
Resque.info
Resque.size :medium
Maybe it will help identify the problem
Trying to update the project to RoR-v4.0.0.rc2 in prep for new release next week, and I am a bit confused about how to fix the dependency issue. If I use bundle update, I get the following error:
Resolving dependencies...
Bundler could not find compatible versions for gem "railties":

Bundler could not find compatible versions for gem "rails":
In Gemfile:
requirejs-rails (>= 0) ruby depends on

But if I use just bundle, I get the following :
Resolving dependencies...
Bundler could not find compatible versions for gem "activesupport":

In Gemfile:

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
Supposedly, requirejs-rail has been updated for Rails 4 Beta here. Still unsure of what dependency is causing the issue, and which version to force the gem to.

The problem is with requirejs-rails gem. You probably should refer to master branch on github in your Gemfile
gem 'requirejs-rails', git: 'git://github.com/jwhitley/requirejs-rails.git'
#Michael Szyndel That branch is not completely rails 4 compatible.
The rake task will fail with an error about 'ruby_rake_task'. Also, the asset pre-compilation is broken. There are rails 4 patches out their but they have yet to be included into master.
This fork has included the rails 4 patches, try that one out.

Can You please help me.
It seems that gem 'twitter-bootstrap-rails' and gem 'less-rails-bootstrap'give error.
I was getting the error during db:create.
C:\Sites\Library>rake db:create
[WARNING] Please install gem 'therubyracer' to use Less.
rake aborted!
cannot load such file -- v8
C:/Sites/Library/config/application.rb:7:in `<top (required)>'
C:/Sites/Library/Rakefile:5:in `<top (required)>'
(See full trace by running task with --trace)
So I removed both of them.Instead I went to 'bootstrap-sass' gem to implement bootstrap in rails and it seems to work fine for me.
Don't know if I am correct
Instead of doing all this, you can just start a project again from scratch.
Please update your gemfile accordingly.
OK now that you've spotted the issue I would recommend to install the 'bootstrap-sass' gem that I know works 100%.
I happened to answer a similar question so here's the link:
how to use that gem and why
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 '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.):

Can anyone offer an explanation as to why bundle install is not installing all the gems listed in my Gemfile?
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.
You have to use bundler to execute rake:
bundle exec rake db:schema:load RAILS_ENV=production
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
I'm experiencing some difficulties when using the command: "bundle install". It's probably some kind of a trivial issue, but I would appreciate any help you can give. I am using linux ubuntu 11.04, ruby 1.9.3p125 (2012-02-16 revision 34643) [i686-linux]

Looks like bundler doesn't have rights to access Gemfile and/or Gemfile.lock make sure the permissions are right on those files.
Being on Ubuntu, you might want to work on your app in /home/<username>/ where you should have more permissions.
If you are working in the /var/ directory, you might need to use sudo everywhere.
