title: RSpec let error
body: <p>In my spec/models/user_spec.rb I have the next:</p>
  
  <pre><code>require 'spec_helper'
  
  describe User do
  
    before { 5.times { FactoryGirl.create(:sport) } }
    before { let(:user) { FactoryGirl.create(:user) } }
  
    ...
  
  end
  </code></pre>
  
  <p>But when running my user_spec.rb I'm getting this error:</p>
  
  <pre><code>Failure/Error: before { let(:user) { FactoryGirl.create(:user) } }
   NoMethodError:
     undefined method `let' for #&lt;RSpec::Core::ExampleGroup::Nested_1:0x000001043033b0&gt;
  </code></pre>
  
  <p>Which is weird because my specs have been working until now, and I haven't changed anything...</p>
  
  <p>Here is my gemfile: <a href="https://gist.github.com/4690919" rel="noreferrer">https://gist.github.com/4690919</a></p>
  
  <p>Here is my spec_helper.rb: <a href="https://gist.github.com/4690935" rel="noreferrer">https://gist.github.com/4690935</a></p>
  
  <p>I'd appreciate any help, thanks</p>
