Jekyll Pagination Path Doesn't Include Page Number

Question

I am attempting to create pagination in Jekyll under the path '/notes/'.

In my _config.yml, I have:

paginate: 2
paginate_path: "/notes/:num/"

In my /notes/index.html, I have:

<div class="pagination">
  {% if paginator.previous_page %}
    <a href="{{ paginator.previous_page_path }}" class="previous section link">Previous</a>
  {% else %}
    <span class="previous section link">Previous</span>
  {% endif %}
  <span class="page_number section">{{ paginator.page }} / {{ paginator.total_pages }}</span>
  {% if paginator.next_page %}
    <a href="{{ paginator.next_page_path }}" class="next section link">Next</a>
  {% else %}
    <span class="next section link">Next</span>
  {% endif %}
</div>

When I load http://localhost:4000/notes, I see that the 'Previous' link is not linking to /notes/2, but instead it simply links to /notes/, the page that I am already on. Additionally, when looking in the generated _site folder, I see that /notes/2 has not been created, despite having more than two posts created.

So, I suppose my question is, how can I fix this and get jekyll to paginate properly?
