[error]: Missing 'commonmarker ' gem for Markdown formatting. Install it with gem install commonmarker

[pboling]

I have commonmarker installed, and in my Gemfile. I am running latest yard, commonmarker, rubygems, bundler, and ruby (3.3.5).

In my Rakefile, I have:

  require "yard"

  YARD::Rake::YardocTask.new do |t|
    t.files = ["lib/**/*.rb"]
    t.options = ["--debug", "--markup", "markdown", "--markup-provider", "commonmarker"]
  end

Steps to reproduce

git clone https://github.com/oauth-xx/ruby-openid2.git
cd ruby-openid2
bundle install
bundle exec rake yard

Actual Output

❯ bundle exec rake yard
[error]: Missing 'commonmarker' gem for Markdown formatting. Install it with `gem install commonmarker`

Expected Output

I expected yard to generate documentation.

Unfortunately, you have to use an older (< 1.0) version of Commonmarker: #1528
