Came across this error when trying out the ruby on rails tutorial section with rspec on a windows platform using jruby 1.6:
c:\\rails_projects\\sample_app>
This might be of some use - in the event rpsec wasn't installed properly on a Win7 environment.
rails3 rspec issue
After running
rails generate rspec:install
Place your *_spec.rb files under (in your example) c:\rails_projects\sample_app\spec\model. Then specify relative path with require_relative
require_relative '../spec_helper'
Run the following command
c:\rails_projects\sample_app>rails generate rspec:install
This will put the spec_helper.rb file in your /spec directory
When you execute 'rails generate rspec:install', if you see 'Could not find generator rspec:install' error message, add gem 'rspec-rails' within :developnent, :test group in your project Gemfile as shown below.
group :development, :test do
gem 'rspec-rails'
end
After this, execute 'bundle install' and continue with 'rails generate rspec:install'
I had the same problem but for a different reason:
in my spork.prefork block within my spec_helper.rb file I had this line
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
but within one of the files that was being required above (spec/support/some_helper_file.rb) was a require 'spec_helper' call
removing this unneeded require solved the issue
