Missing kramdown-parser-gfm

[mroberts1]

Local install fails due to missing gem kramdown-parser-gfm, even after installing the gem. Kramdown 2.4.0 is also installed.

Tried with 3 versions of Ruby: 2.7.8, 3.1.4, 3.2.2.

Hi @mroberts1.

It seems I've missed a couple of notifications from this repo, probably my fault, I might have accidentally marked as read. For this I apologize.

Could you please provide a few more details about the issue you are facing? For example the version of Bundler you are using, the commands you are running and the output error messages. This would really help.

It could be something in your system too. Have you tried to install it using a container to separate your system from the running environment?

To make sure it doesn't works only on my machine I did this (requires Docker installed):

• Speed up a new container with Ruby 3.2.2.

  docker run --rm -it -p 4000:4000 -w /app ruby:3.2.2-bullseye bash

• Inside the container cloned the repository.

  
  git clone https://github.com/julianolf/jekyll-theme-8bit.git

* Moved inside the directory and tried to install the dependencies.
```sh
cd jekyll-theme-8bit/

bundle install

Could not find compatible versions

Because the current Bundler version (2.4.10) does not satisfy bundler ~> 2.2.0
  and Gemfile depends on bundler ~> 2.2.0,
  version solving has failed.

Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with `gem install bundler:2.2.34` and rerun bundler using `bundle _2.2.34_ install`

• It complained about the Bundler version, so I installed the required version as suggested and then used that version to install the dependencies.

  
  gem install bundler:2.2.34 && bundle _2.2.34_ install

A new release of RubyGems is available: 3.4.10 → 3.4.17! Run gem update --system 3.4.17 to update your installation.

```sh

After this I could check it was working by heading to http://127.0.0.1:4000 on my web browser.

@mroberts1 I might have been able to reproduce the error you mentioned.

After updating both Ruby and Bundler to the latest versions I also updated all dependencies and tried to run Jekyll's local server and that was when I got an error:

Dependency Error: Yikes! It looks like you don't have kramdown-parser-gfm 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 -- kramdown-parser-gfm' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!
  Conversion error: Jekyll::Converters::Markdown encountered an error while converting '_posts/2019-01-23-a-post.md':
                    kramdown-parser-gfm
             ERROR: YOUR SITE COULD NOT BE BUILT:
                    ------------------------------------
                    kramdown-parser-gfm

With some research on Internet I found an issue on Jekyll's GitHub page telling that its development server has this dependency when running on Ruby > 3.0, and the solution just required to add that gem to the Gemfile.

On my next attempt to run the server I got a new error, another required dependency, webrick, once again added to Gemfile.

This changes fixed the problem for me, maybe they will do the same for you.

I pushed those changes and I'll be publishing a new version of the theme, if you try it and still have issues let me known.
