Jekyll build error GemNotFound on fresh clone of workshop-template

[ilessing]

when I clone this repository and issue the make serve command I get the following error:

~/.gem/ruby/2.6.0/gems/bundler-2.1.1/lib/bundler/resolver.rb:290:in `block in verify_gemfile_dependencies_are_found!': Could not find gem 'github-pages' in any of the gem sources listed in your Gemfile. (Bundler::GemNotFound)

Environment:

Mac OS 10.15.2 Catalina

% ruby -v         
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-darwin19]

% jekyll -v
jekyll 4.0.0

If I remove the Gemfile rm Gemfile the make serve succeeds.

Thanks @ilessing for taking the time to document your issue (and solution)! I'll assign this issue to @fmichonneau.

Hi @ilessing
Thanks for the report!
I just brought the latest changes to our general styles (#645) which among other fixes has a revamped Makefile that uses bundle exec jekyll serve to generate the website locally and should address the error you saw.
