Error: no implicit conversion of nil into String #18

Closed Frozenfire92 closed 8 years ago

Frozenfire92 commented 8 years ago

When switching from jekyll-paginate to octopress so I can paginate collections I get the following error

Configuration file: /home/.../website/_config.yml
       Deprecation: You appear to have pagination turned on, but you haven't included the `jekyll-paginate` gem. Ensure you have `gems: [jekyll-paginate]` in your configuration file.

  Liquid Exception: no implicit conversion of nil into String in _tutorials/2016-01-10-welcome-to-jekyll.markdown
jekyll 3.0.1 | Error:  no implicit conversion of nil into String

Here is my config file

# Blog settings
permalink: /blog/:year/:month/:day/:title
paginate: 6
paginate_path: "/blog/page/:num"

# Tutorial settings
collections:
  - tutorials

# Plugins
gems:
- octopress-paginate

Here is my tutorials index file tutorials/index.html


---
layout: page
nav_layout: tutorial
title: Tutorial Index
paginate:
  collection: tutorials
  permalink: /tutorials/:year/:month/:day/:title

---
{% for tutorial in paginator.tutorials %}
        ...
{% endfor %}

Then I have markdown files in the folder _tutorials

I think this is related to https://github.com/jekyll/jekyll/issues/3929 and https://github.com/octopress/hooks/issues/13

Maybe relevant info

Yeah, I have a very similar issue with the "no implicit conversion of nil into String (TypeError)" (although I don't get the "Deprecation: Collection#reverse should be called on the #docs array directly." bit).

I was having this problem with my jekyll site and tried to narrow it down by stripping everything out bit by bit. I got down to stripping everything out and it was still there.

Turns this was nothing to do with my site, but happens with a fresh, brand new install of jekyll with the octopress-paginate gem specified in the Gemfile.

Here are the steps I took to create reproduce the issue:

mkdir test
cd test
bundle init
echo "gem 'jekyll'" >> Gemfile
echo "group :jekyll_plugins do" >> Gemfile
echo "  gem 'octopress-paginate'" >> Gemfile
echo "end" >> Gemfile
bundle install
bundle exec jekyll new site
bundle exec jekyll build -s site --trace

Here is the jekyll output when using ruby2.3 on Ubuntu Trusty LTS:

This appears to be related to https://github.com/octopress/hooks/pull/14; I am hoping a fresh release of octopress-hooks with that fix included will also fix the issue.

japilo commented 8 years ago

I am still having this exact same issue with a fresh install of jekyll and octopress, for what it's worth.

I pulled lib from octpopress-hooks https://github.com/octopress/hooks/commit/9ec9efcbe8e2aa4d79d2a35543a29b51f3e6feb2

and issue no longer occurs on jekyll build. Thanks@parkr !

@parkr: this must be the same issue as #19
