After the upgrade to 3.0.7, I cannot build my Alembic-themed jekyll sites anymore. I tried on an Arch Linux machine (ruby 2.5.3p105) and within an Alpine-based docker container (don't know the Ruby version there). I always get this error:

  Dependency Error: Yikes! It looks like you don't have liquid-c or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- liquid-c' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/! 

I can reproduce this using the following minimal example with only two files:

Gemfile:

source "https://rubygems.org"
gem "jekyll"
gem "alembic-jekyll-theme"

_config.yml

theme: alembic-jekyll-theme

bundle install && bundle exec jekyll serve results in the above error. Adding gem "liquid-c" to Gemfile does not help. I am not a Ruby guy, I may have missed something I need to do. But to me, this looks like a bug in the theme. It would be great if you could take a look!

Hey @MJochim, sorry you're having trouble with the new version of Alembic. Seems odd that it's not installing liquid-c, the reference for the gem is right here https://github.com/daviddarnes/alembic/blob/master/alembic-jekyll-theme.gemspec#L29. I'll have a go installing a fresh to see if I get the error. Have you tried installing outside the docker container as a plain Jekyll project? Also, what version of Jekyll are you using?

[MJochim]

Yes, the Arch Linux machine is non-docker. I'm using Jekyll 3.8.5:

$ bundle exec jekyll --version
jekyll 3.8.5
$ jekyll --version
jekyll 3.8.5
$ ruby --version
ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-linux]

Just now I deleted liquid-c manually ($GEM_HOME/gems/liquid-c-4.0.0 and $GEM_HOME/specifications/liquid-c-4.0.0.gemspec) and then re-executed bundle install && bundle exec jekyll serve. The result is:

[…]
Using jekyll-sitemap 0.13.0
Using gemoji 3.0.0
Using jemoji 0.10.2
Fetching liquid-c 4.0.0
Installing liquid-c 4.0.0 with native extensions
Using alembic-jekyll-theme 3.0.7
Using bundler 1.17.1
Bundle complete! 2 Gemfile dependencies, 48 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

So it does re-install liquid-c (and I can confirm that by looking at $GEM_HOME/gems/liquid-c).

But the error message from bundle exec jekyll serve remains.

having the same problem. downgrading to 3.0.6 fixes.

[daviddarnes]

Well it's nice to know people are keeping up to date and using the theme, but sad I've broken your stuff :(. I've released 3.0.8 which removes liquid-c entirely, could you report back if it's working? Thanks all!

[MJochim]

Well, thank you for your exceptionally fast response - and for the theme in the first place :-).

Upgrading to 3.0.8 works perfectly.
