title: Error: uninitialized constant WillPaginate::ActionView (NameError) when using generator with Pundit
body: <p>My app was using CanCan but now I'd like to switch to Pundit. I added Pundit to the Gemfile, deleted CanCan, ran <code>bundle</code> and then, when trying to run the generator (<code>rails g pundit:install</code>), I got the error:</p>
  
  <pre><code>...config/initializers/bootstrap_link_renderer.rb:1:in `&lt;top (required)&gt;': uninitialized constant WillPaginate::ActionView (NameError)
  </code></pre>
  
  <p>Here is my application_controller.rb file:</p>
  
  <pre><code>class ApplicationController &lt; ActionController::Base
    include Pundit
  
    # Prevent CSRF attacks by raising an exception.
    # For APIs, you may want to use :null_session instead.
    protect_from_forgery with: :exception
  
    before_filter :configure_permitted_parameters, if: :devise_controller?
  
    def configure_permitted_parameters
      devise_parameter_sanitizer.for(:account_update) &lt;&lt; :avatar
    end
  
    def after_sign_in_path_for(resource)
      topics_path
    end
  end
  </code></pre>
  
  <p>Here is the bootstrap link renderer:</p>
  
  <pre><code>class BootstrapLinkRenderer &lt; WillPaginate::ActionView::LinkRenderer 
    def html_container(html)
      tag(:ul, html, container_attributes)
    end
  
    def page_number(page)
      tag :li, 
      link(page, page, rel: rel_value(page)), 
      class: ('active' if page == current_page)
    end
  
    def gap
      tag :li, 
      link(super, '#'), 
      class: 'disabled'
    end  
  
    def previous_or_next_page(page, text, classname)
      tag :li, link(text, page || '#')
    end
  
    def previous_page
      num = @collection.current_page &gt; 1 &amp;&amp; @collection.current_page - 1
      previous_or_next_page(num, '&amp;laquo;', 'previous_page')
    end
  
    def next_page
      num = @collection.current_page &lt; total_pages &amp;&amp; @collection.current_page + 1
      previous_or_next_page(num, '&amp;raquo;', 'next_page')
    end
  end
