Jekyll Scholar on macOS 10.13.6: Tried to create Proc object without a block

Why are you trying to make this run using old Gems? I don't think the old macOS version should give you any problems as long as you've installed a sufficiently recent version of Ruby. The error message above is certainly caused by some combination of running the Gem with an incompatible Ruby version. So if possible, I'd try to install the latest versions of jekyll and jekyll-scholar.

If there's some other reason why you have to stick with an older version of either of the two that's another matter of course. To answer your question it looks like this commit broke with jekyll 3.x. It was tagged 7.1.3 so I'd guess that the versions before that should work with jekyll 3.9.

I tried running the latest and greatest Ruby, Jekyll and Jekyll-Scholar, but serving the website locally failed with the 'sass' gem error: Jekyll::Converters::Scss:

Conversion error: Jekyll::Converters::Scss encountered an error while converting 'assets/main.scss':
                    end of file reached
bundler: failed to load command: jekyll (/Users/mabalenk/.rbenv/versions/3.2.2/bin/jekyll)

I posted more details on the Jekyll forum. Maybe you know how to solve it? As a workaround I decided to downgrade Jekyll to 3.9.3. This brought a cascade of changes to Ruby and Jekyll-Scholar.

I will try to follow your suggestion. Thank you for your help!

I just tried using v7.1.2 of Jekyll-Scholar. It depends on Jekyll 4 and therefore fails:

Fetching gem metadata from https://rubygems.org/.........
Resolving dependencies...
Could not find compatible versions

Because jekyll-scholar >= 6.0.0 depends on jekyll ~> 4.0
  and Gemfile depends on jekyll = 3.9.3,
  jekyll-scholar >= 6.0.0 cannot be used.
So, because Gemfile depends on jekyll-scholar = 7.1.2,
  version solving has failed.

I need the latest version compatible with Jekyll v3.9.3. Can you please suggest one?

Versions 5.x should be good.

However, I'd really stay up on the latest Gem versions and instead figure out if there's an alternative sass/scss Gem you can use. Judging by the error message you posted the native code used by newer sass versions may not work on your OS so maybe that's why the conversion fails (or there's an sass/scss issue in your stylesheet).
