Jekyll on Nixos

6 minute read

Published:

Back when I used to help my Fachschaft with their website 1 , I would be able to run things locally to see how my blog worked before publishing it the main branch. This is supposedly following good coding practices, as oppsing to yoloing it everytime and modifying the main branch.

Back then, I could just do a nix shell and add jekyll and bundler, and then do bundle exec jekyll serve and it would work.

Unfortuantely, becuase I use nixos, life is hard. And by life is hard, I mean that doesn’t work anymore.

I run it and…

Could not find jekyll-3.10.0, jekyll-feed-0.17.0, jekyll-sitemap-1.4.0, jekyll-redirect-from-0.16.0, jemoji-0.13.0, webrick-1.9.2, github-pages-232, connection_pool-2.5.0, addressable-2.8.9, colorator-1.1.0, csv-3.3.5, em-websocket-0.5.3, i18n-1.14.8, jekyll-sass-converter-1.5.2, jekyll-watch-2.2.1, kramdown-2.4.0, liquid-4.0.4, mercenary-0.3.6, pathutil-0.16.2, rouge-3.30.0, safe_yaml-1.0.5, gemoji-4.1.0, html-pipeline-2.14.3, github-pages-health-check-1.18.2, jekyll-avatar-0.8.0, jekyll-coffeescript-1.2.2, jekyll-commonmark-ghpages-0.5.1, jekyll-default-layout-0.1.5, jekyll-gist-1.5.0, jekyll-github-metadata-2.16.1, jekyll-include-cache-0.2.1, jekyll-mentions-1.6.0, jekyll-optional-front-matter-0.3.2, jekyll-paginate-1.1.0, jekyll-readme-index-0.3.0, jekyll-relative-links-0.6.1, jekyll-remote-theme-0.4.3, jekyll-seo-tag-2.8.0, jekyll-swiss-1.0.0, jekyll-theme-architect-0.2.0, jekyll-theme-cayman-0.2.0, jekyll-theme-dinky-0.2.0, jekyll-theme-hacker-0.2.0, jekyll-theme-leap-day-0.2.0, jekyll-theme-merlot-0.2.0, jekyll-theme-midnight-0.2.0, jekyll-theme-minimal-0.2.0, jekyll-theme-modernist-0.2.0, jekyll-theme-primer-0.6.0, jekyll-theme-slate-0.2.0, jekyll-theme-tactile-0.2.0, jekyll-theme-time-machine-0.2.0, jekyll-titles-from-headings-0.5.3, kramdown-parser-gfm-1.1.0, minima-2.5.1, nokogiri-1.19.2-x86_64-linux-gnu, terminal-table-1.8.0, public_suffix-5.1.1, eventmachine-1.2.7, http_parser.rb-0.8.1, concurrent-ruby-1.3.6, sass-3.7.4, listen-3.10.0, rexml-3.4.4, forwardable-extended-2.6.0, activesupport-8.1.3, dnsruby-1.73.1, octokit-4.25.1, typhoeus-1.6.0, coffee-script-2.4.1, coffee-script-source-1.12.2, commonmarker-0.23.12, jekyll-commonmark-1.4.0, rubyzip-2.4.1, racc-1.8.1, unicode-display_width-1.8.0, sass-listen-4.0.0, logger-1.7.0, rb-fsevent-0.11.2, rb-inotify-0.11.1, base64-0.3.0, bigdecimal-4.0.1, drb-2.2.3, json-2.19.3, minitest-6.0.2, tzinfo-2.0.6, uri-1.1.1, simpleidn-0.2.3, faraday-2.14.1, sawyer-0.9.3, ethon-0.18.0, execjs-2.10.0, ffi-1.17.3-x86_64-linux-gnu, prism-1.9.0, faraday-net_http-3.4.2, net-http-0.9.1 in locally installed gems

Ok, cool. I guess I’ll run bundle install. Even though I’m pretty sure it’s not the “nix way”. Whatever, let’s give it a shot:

An error occurred while installing bigdecimal (4.0.1), and Bundler cannot
continue.

In Gemfile:
  github-pages was resolved to 232, which depends on
    jekyll-mentions was resolved to 1.6.0, which depends on
      html-pipeline was resolved to 2.14.3, which depends on
        activesupport was resolved to 8.1.3, which depends on
          bigdecimal

Oof, looks like it din’t work.

What’s really stupid, is that I think I figured out how to run it back in March/April. Unfortunately, I did not write down how I did it. And when I just made my blog post, I could not figure out how to test it.

Ok, time to do some detective work and retrace my steps. Looking at my browser history, I see I visited this guy, and looks like there is this guy working for deltachat.

And would you look at that, I had already shamelessly copy pasted his flake.nix. I didn’t even change it from deltachat lol.

And it also didn’t work.

Finally, looked at the source for jekyll. And this helpful part here gave me a hint

echo 'Skipping "bundle install" as it fails due to the Nix wrapper.'
echo 'Please enter the new directory and run the following commands to serve the page:'
echo 'nix-shell -p bundler --run "bundle install --gemfile=Gemfile --path vendor/cache"'
echo 'nix-shell -p bundler --run "bundle exec jekyll serve"'
exit 0

Well, that seemed to solve the issue. I don’t know why the flake.nix. Maybe someone smarter than me can tell me why.

Communicating in relationships

Something I learned that is really important in romantic relationships is to communicate effectively. Looking back, I realize I was very afraid to bring up certain topics. So, I simply avoided it.
