This indicates text that should be entered into terminal

###configuration###

sudo add-apt-repository ppa:webupd8team/sublime-text-2
sudo apt-get update

###programs###

  • Install packages
sudo apt-get install git-core curl ruby1.8-dev ruby1.8 ri1.8 rdoc1.8 irb1.8 libreadline-ruby1.8 libruby1.8 libopenssl-ruby libxslt-dev libxml2-dev libxslt1-dev postgresql postgresql-contrib libpq-dev nodejs sublime-text

###rbenv###

Install rbenv and the latest versions of Ruby and Rails (this next line goes into the terminal, remember):

git clone https://github.com/sstephenson/rbenv.git ~/.rbenv

 echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile

echo 'eval "$(rbenv init -)"' >> ~/.bash_profile && source ~/.bash_profile

git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

rbenv install 2.0.0-p353

Now setup the default version of ruby

rbenv global 2.0.0-p353

Now let's get you the rails version we're using for the weekend. Add the gems with:

gem install rails -v 4.0.0

rbenv rehash

And if you type:

rails -v

You should get: Rails 4.

Now open a new tab in the terminal (Command+t) and type in:

rails -v

Still shows "Rails 4.0? High five you're all set :)

Configure Postgres User Account###

sudo -u postgres psql postgres
\password postgres

When prompted for a password (and a confirmation) enter: password.

Press ctrl+d to close the postgres console.

###Install Nokogiri RubyGem###

Nokogiri is a rubygem that we need and it requires certain packages to be installed. To install those packages and make sure the gem can be installed run these commands:

gem install nokogiri -v 1.5.11

Accounts

Now follow the guide here to setup your web development accounts.

Additional Info

database.yml

We'll go over what this means Saturday.

This installer will install postgresql in such a way that you'll need to adjust your database.yml file to look like this in each of the three sections (development, test, production). Also be sure to adjust the database section. NOTE: indentation is super important - make sure they line up and rather than copy & pasting this, type this in):

development:
  adapter: postgresql
  encoding: unicode
  database: YOUR_APPLICATION_NAME_HERE_development
  pool: 5
  username: postgres
  password: password
  host: localhost
