Trouble with step 1.2.5 of Ruby on Rails tutorial, booting webrick and connecting to localhost:3000

Hello everyone,

I am a total beginner to ruby and rails, but am really excited about
learning the environment. I have to say, however, starting up with RoR
is
certainly most difficult!

I am following along the Ruby on Rails tutorial found at
railstutorial.org
and I have gotten stuck at step 1.2.5. I am running on a windows 8
environment using cmd.exe and sublime text 2 for text editing. I have
updated my gemfile in my first_app project to exactly as it says to do
in
the railstutorial and have ran ‘bundle update’ & ‘bundle install’ and
that
seems to be correct, to me.
My gemfile looks like:

source ‘https://rubygems.org
ruby ‘1.9.3’
#ruby-gemset=railstutorial_rails_4_0

gem ‘rails’, ‘4.0.5’

group :development do
gem ‘sqlite3’, ‘1.3.8’
end

gem ‘sass-rails’, ‘4.0.1’
gem ‘uglifier’, ‘2.1.1’
gem ‘coffee-rails’, ‘4.0.1’
gem ‘jquery-rails’, ‘3.0.4’
gem ‘turbolinks’, ‘1.1.1’
gem ‘jbuilder’, ‘1.0.2’

group :doc do
gem ‘sdoc’, ‘0.3.20’, require: false
end
Which is exactly as it appears in the gemfile editing step of 1.5 in the
railstutorial…

With my gemfile in order and bundled, I type the command ‘rails server’
and
my console spits out a bunch of extra code which is not listed in the
tutorial.
Tutorial says my output should look like:

$ rails server
=> Booting WEBrick
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

But my console outputs much more than that…
C:\Sites\rails_projects\first_app>rails server
=> Booting WEBrick
=> Rails 4.0.5 application starting in development on
http://0.0.0.0:3000
=> Run rails server -h for more startup options
=> Ctrl-C to shutdown server
Exiting

So after this I attempt to point my browser to the localhost server
which I
have supposedly created @ http://0.0.0.0:3000
At this point, I get the “webpage is not available” / “oops! Google
chrome
cannot connect to localhost:3000” error page…

Is there some readily aparant thing I am doing wrong here? I installed
ruby using the Rails Installer for windows utility, if that makes any
difference. I have Java installed, which the author of railstutorial
mentions may be an issue in respect to javascript…

Can anyone help me?

Best regards,
Will

Look at what the error is telling you:

C:/Sites/rails_projects/first_app/config/environments/development.rb:1:in
<top (required)>': undefined methodconfigure’ for
#<FirstApp::Application:0x273df20

(NoMethodError)

Generally, the exception is “*NoMethodError” *means that the interpreter
was not able to find a method (in this case “configure”) in a specific
file (in this case “*development.rb”. *It even tells you the line, which
is
after the colon "1").

Can you provide the contents of the development.rb file and of any other
file that you perhaps are “requiring” inside of it ?

Antonio,

Thanks for your response. That error code makes a bit more sense to
me
now, I appreciate your response.
Here are the contents of my development.rb file

Rails.application.configure do

Settings specified here will take precedence over those in

config/application.rb.

In the development environment your application’s code is reloaded

on

every request. This slows down response time but is perfect for

development

since you don’t have to restart the web server when you make code

changes.
config.cache_classes = false

Do not eager load code on boot.

config.eager_load = false

Show full error reports and disable caching.

config.consider_all_requests_local = true
config.action_controller.perform_caching = false

Don’t care if the mailer can’t send.

config.action_mailer.raise_delivery_errors = false

Print deprecation notices to the Rails logger.

config.active_support.deprecation = :log

Raise an error on page load if there are pending migrations.

config.active_record.migration_error = :page_load

Debug mode disables concatenation and preprocessing of assets.

This option may cause significant delays in view rendering with a

large

number of complex assets.

config.assets.debug = true

Adds additional error checking when serving assets at runtime.

Checks for improperly declared sprockets dependencies.

Raises helpful error messages.

config.assets.raise_runtime_errors = true

Raises error for missing translations

config.action_view.raise_on_missing_translations = true

end

As far as I can tell, the first line is not missing and loads a method
known as configure. I however did not write a configure method, nor did
the railstutorial outline the need for one… I can see the problem is
now
that this configure method is undefined, but how do I go about resolving
this?

Much obliged,
Will
