I'm working through chapter 3 of Michael Hartl's tutorial and I tried running "rails generate rspec:install" and I get the error message below.

C:\Sites\sample_app>rails generate rspec:install

Here is my gemfile

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.8'

group :development, :test do
  gem 'sqlite3', '1.3.8'
  gem 'rspec-rails', '2.13.1'
end

group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
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

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

The first line of my config/enivronments/development.rb file

Rails.application.configure do

I looked up some other answers to this question. And they suggested changing the first line in my development.rb file to SampleApp:Application.configure.do; but that just leads to another error 'unitialized constant SampleApp'. So I I changed it back to default.

EDIT: Fixed it to SampleApp::Application, got this cmd line message after running "rails generate rspec:install"

C:\Sites\sample_app>rails generate rspec:install
DL is deprecated, please use Fiddle
      create  .rspec
      create  spec
      create  spec/spec_helper.rb

  • Can you post the first line of your `development.rb` file? in `app/config/environments/development.rb`. Also, when you ran the `rails new ...` generator command, what did you name your app..`SampleApp`?? – Justin Jul 05 '14 at 17:28
  • Thanks, ok change the first line to `SampleApp::Application.configure do`. Looks like you missed the double `::`. If that doesn't work, I have one more suggestion that may fix it. – Justin Jul 05 '14 at 17:30
  • Hi, that might have been the trick. Can you look at my new cmd line message above and tell me if it worked correctly? – user3808138 Jul 05 '14 at 17:53
  • Yes that created the necessary files to use `Rspec`. Updated my answer below. – Justin Jul 05 '14 at 17:55
  • Thanks do I have to worry about "DL is deprecated, use fiddle instead"? – user3808138 Jul 05 '14 at 17:59
  • Nope, it's just a warning for Windows. I assume you are running on Windows. Here is a good [S.O. post](http://stackoverflow.com/a/15601984/2456549) that talks about it. – Justin Jul 05 '14 at 18:02

Thanks, ok change the first line to 

SampleApp::Application.configure do

Looks like you missed the double ::.

Credit to this S.O. answer.

  • Sorry I actually made a mistake in my question. I tried to do "rails generate:install" And I got the above error – user3808138 Jul 05 '14 at 17:23
