I had the same issue. But I got it to work by rolling back to Jekyll 3.9.3.

dieghernan · 2024-02-09T10:19:19Z

Thanks to @SatyajithBoyana suggestion I was able to fix this. Also mentioned in https://talk.jekyllrb.com/t/local-windows-dev-environment-for-github-pages-theme/8938

See dieghernan/chulapa@f508ba1

Also running into this on gh pages, where you cannot specify the Jekyll version

monfresh · 2024-02-10T00:00:02Z

You can definitely specify the Jekyll version on GitHub Pages, and even use Jekyll 4. The trick is to use GitHub Actions instead of the github-pages gem.

https://github.blog/2022-08-10-github-pages-now-uses-actions-by-default/#how-can-i-upgrade-to-jekyll-4

You can also try my guide, although it's a bit outdated: https://www.moncefbelyamani.com/making-github-pages-work-with-latest-jekyll/

monfresh · 2024-02-10T00:02:23Z

Also, even if you're still using the github-pages gem, you can specify the Jekyll version by specifying the github-pages gem version. For example, if you set the gem to version 228, it will use Jekyll 3.9.3: https://rubygems.org/gems/github-pages/versions/228

You can pin the version like this in your Gemfile:

gem "github-pages", "=228"

pettazz · 2024-02-10T00:11:34Z

Yes, sure, but I'm just talking about the built in gh pages functionality. I don't want to have to reconfigure the whole site because there appears to be an issue in one version of Jekyll.

Pinning the github-pages version does not appear to work, the builder uses the versions it wants regardless with the message:

Warning: The github-pages gem can't satisfy your Gemfile's dependencies.

I think the gem is meant for easily replicating the builder environment on your local machine rather than telling the builder what to use.

monfresh · 2024-02-10T00:26:22Z

You're right. I forgot about that, and I even mention it in my guide. That's why I recommend using GitHub Actions since you have more control over the gem versions, and you can take advantage of Jekyll 4's improvements.

Alternatively, as mentioned in my guide, you can build your site locally with Jekyll 3.9.3, and then push the contents of the _site folder to a branch called gh-pages, and GitHub will serve the contents directly without building.

QuantKang · 2024-02-10T11:41:12Z

A simple way to work around this issue is defining a new workflow by copying Jekyll workflow:

Go to your repository
Click Action menu
Press New workflow button
Search Jekyll
Find the workflow named Jekyll and click Configure button
Press Commit changes

You may need to pull and push from your local repository to sync with the commit.

The workflow seems designed for the latest stable Jekyll. It uses Jekyll 4.3.3.

pettazz · 2024-02-10T15:30:04Z

It's not that simple if you've been dragging the same Jekyll site around for nearly a decade and it doesn't work on 4.x without some changes.

marksherriff · 2024-02-10T15:31:54Z

For those having this issue specifically with the academicpages template (evidenced potentially by specifically the 404.md file error), it turns out if you remove the excerpt line from 404.md, about.md, and non-menu-page.md, everything deploys properly.

If you build your site with Actions (which is the majority of cases), your build should be fixed now. The change made it in https://github.com/actions/jekyll-build-pages/releases/tag/v1.0.11.

Still deploying the changes to Pages' legacy infrastructure now.

Thanks @parkr for patching Jekyll for us ❤ and sorry for all the troubles.

toddhgardner · 2024-02-13T19:00:12Z

@parkr @yoannchaudet I hate to be a pain, but 3.9.5 is broken for me with a new error:

/usr/local/bundle/gems/jekyll-3.9.5/lib/jekyll/excerpt.rb:91: warning: Jekyll::Excerpt#yaml_file? at /usr/local/lib/ruby/2.7.0/forwardable.rb:154 forwarding to private method Jekyll::Page#yaml_file?
  Liquid Exception: undefined method `yaml_file?' for #<Jekyll::Page @name="dpa.md"> in /_layouts/empty.html

That error is from the Github pages build, and I see the same error locally with 3.9.5 on multiple sites. I don't think that's an issue with my setup, but for completeness, here is what those files look like for me:

/_layouts/empty.html is my basic layout, it has no front-matter

<!DOCTYPE html>
<html lang="en" class="no-js">
  {% include head.html %}
  <body class="{{ layout.body_class }} {{ page.body_class }} preload">
    <script>document.documentElement.classList.remove("no-js");</script>
    {{ content }}
    {% include scripts.html %}
    <script>document.body.classList.remove("preload");</script>
  </body>
</html>

dpa.md is a regular page in my site. Here is the start of the file

I can confirm I am getting the same error as @toddhgardner after upgrading github-pages to 230 in remarkablemark/remarkablemark.github.io#71 (comment)

chadpav · 2024-02-13T22:33:49Z

Not regretting my decision to spend 5 minutes moving to a custom GitHub action and controlling what version of Jekyll is used.

yoannchaudet · 2024-02-13T23:51:50Z

@chadpav This is the way 🙈.

@toddhgardner Thanks for providing an example that trips the exception. I'll try and revert jekyll-relative-links to 0.6.1. I suspect this is the root cause of the issues we are seeing (changelog).

Solve the problem where jekyll would fail now at building pages because of not finding the command "excerpt." Problem is documented here: https://stackoverflow.com/questions/77972098/github-jekyll-page-build-keeps-failing and jekyll/jekyll#9544 and academicpages/academicpages.github.io#1878

Per: jekyll/jekyll#9544

ShaneCurcuru · 2024-02-14T17:54:48Z

(aside) I totally get "you should just use a GH Pages Action like so..." But the popularity - and simplicity! - of GH Pages "just working out of the box" is huge, and it was disappointing (on GH's part, really, not your's!) that this now suddenly is breaking deploys to GHPages sites people thought were zero maintenance.

In any case, thanks Jekyll peeps for building and maintaining such an awesome system! 🥰

yoannchaudet · 2024-02-15T02:47:55Z

Second time a charm?

We sent pages-gem v231 everywhere. It reverted (for now) jekyll-relative-links to the previous release. Hopefully that clears up all the issues.

Let us know!

remarkablemark · 2024-02-15T02:56:21Z
