Error when running Jekyll

@kisvegabor I tried installing the latest version of Ruby and Jekyll according to the link you provided.
When running bundle exec jekyll serve in blog, I get the following error:

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (~> 1.12)

  Current Bundler version:
    bundler (2.0.1)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (~> 1.12)' in any of the relevant sources:
  the local ruby installation

My Bundler version:

$ gem list bundler

*** LOCAL GEMS ***

bundler (2.0.1, default: 1.17.3)

I really know nothing about Ruby and Jekyll. Could you help?

I also don't know too much about it. You are also on Linux, right?

I tried a lot of things when set-up the blog so maybe there is an extra command which is still required.

Have look at this: https://stackoverflow.com/questions/49848116/bundler-cant-resolve-the-correct-dependent-version-of-a-gem-thats-manually-i?rq=1

If it doesn't solve the issue I'll set-up a virtual machine to test it.

Ok.
After some digging, I found how to install the correct version of Bundler and use it on Blog:

gem install bundler -v 1.12
bundle _1.12_ install

Worth updating the README...

Closing.

Great!

As it's working here I can't test it right now. Can you add the required hint to the REAMDE?

Can you add the required hint to the REAMDE?

Sure, I'll add it when I push my post about lvgl+micropython.

Great, thank you!
