Installation issue on Ubuntu 22.04

Help

Hello,

I’m on Ubuntu 22.04, Ruby Version 3.0.2, Gem Version 3.3.5. I’ve followed installation process over here:

And I stuck at the last piece:

gem install jekyll bundler

results in

Building native extensions. This could take a while...
ERROR:  Error installing jekyll:

I’ve already installed these dependencies:

  • ruby-dev
  • build-essential
  • g++
  • make
  • libffi-dev
  • gcc
  • ruby-full
  • zliblg-dev
  • rbenv
  • ubuntu-dev-tools
  • ruby-all-dev
  • ruby3.0-dev

Thanks for your Help.

you get this error when the ruby dev tools are not installed but I see you say you have them.

My guess is you have ruby installed more than once and one has it the other doesn’t.

I would remove ruby and start over.

Your error message seems to show it is using ruby 3.0.0.

If the suggestion by @rdyar does not work, I created the following video that shows how to build Jekyll in a Ubuntu Docker container. While I think you are not using Docker, you can watch this video to see the steps I used if that is helpful.

Thank you @rdyar for your reply. Unfortunately uninstall and reinstall ruby by apt didn’t helped. Maybe I need a certain ruby version but in the end I didn’t follow this way no more.

@BillRaymond thanks for introducing docker to me. Though I’m not a video guy and didn’t watched you tutorial to the end. I got jekyll running on my machine by the Bret Fisher way in the end.
