Installing RSpec in Rubygem

Question

I have decided to create my first gem and now I'm trying to install RSpec.

I have added spec.add_development_dependency "rspec", "~> 2.14" to my .gemspec file and I have created spec/spec_helper.rb as below

require 'rubygems'
require 'bundler/setup'
Bundler.require(:default, :development)

require 'my_gem' 


RSpec.configure do |config|
  config.color_enabled = true
  config.formatter     = 'documentation'

  config.order = 'random'
end

After bundle it up, I have finally added spec/foobar_spec.rb as below

require 'spec_helper'

describe 'foobar' do
  expect(1).to eq(2)
end

But when I run rspec spec/foobar_spec.rb I get

undefined method `expect' for # (NoMethodError)

Am I missing something here?

Thanks

According to the Rspec docs, expectations must be defined within it blocks:

describe 'foobar' do
   it { expect(1).to eq(2) }
end
