Freshly installed jekyll gives weird error

Help
1

Hi, I installed jekyll and things seemed to work. I started to configure it to my needs and then suddenly I got the error below. Ever since I have not been able to get rid of this error. I did a complete reinstall of jekyll and bundle and all local gems, created a new projects from scratch, but nothing helps.

Can someone please help me debug what is wrong?

I create a new directory:

jekyll new docs2
cd docs2

And then run:

daniel:~/projects/aicxx/linuxviewer/linuxviewer/docs2>bundle exec jekyll serve --trace

it kinda looks like you have ruby stuff in 2 different places. Try uninstalling ruby and then re-install it.

3

Can you tell me which those two places are? I never used ruby before imho, nor jekyll or bundle or anything :/. So I have no idea how to even “reinstall”. That is, I believe something was already installed when I tried to install jekyll yesterday. When running bundle install I did get an error about not having permission to write to /usr/share/something I think, owned by root. This should be normal though: I am using Arch linux and that also installs gems system wide (using pacman). I found on the arch wiki (I think it was) that I had to set the environment variable GEM_HOME using:

export GEM_HOME="$(ruby -e 'puts Gem.user_dir')"

which I added to my ~/.bashrc now.
That sets GEM_HOME to /home/carlo/.local/share/gem/ruby/3.0.0

I tried to get help (and it helped with a lot of things correctly) from GPT-4, although I am very aware that chatgpt and GPT-4 too at times can say completely wrong things with confidence; I always verify the suggested things. Nevertheless, that has led me to attempt a reinstall as follows:

rm -rf docs # The jekyll project directory.
rm -rf ../linuxviewer-objdir # The build directory of my project, which included the `_site` and jekyll cache.
yay -R jekyll # It was GPT-4 in the first place who told me to use yay for jekyll on Arch (I have installed yay freshly too, yesterday). This removes jekyll.
gem uninstall bundler # Get rid of the installed bundler.
rm -rf ~/.local/share/gem/ruby/3.0.0 # Remove all local gems (see GEM_HOME above).
yay -S jekyll # Reinstall jekyll
gem install bundler # Reinstall bundler
jekyll new docs # Recreate the jekyll project directory

At this point I did STILL get the same error (see above).
But then I did:

bundle install

I guess I had forgotten that…
The error now changed, and required me to do:

bundle add webrick

(A solution found on https://github.com/jekyll/jekyll/issues/8523 by Googling for that error).
After that, bundle exec jekyll serve worked again. Then I made the changes that I had made before to _config.yml, being:

...
destination: /home/carlo/projects/aicxx/linuxviewer/linuxviewer-objdir/linuxviewer-docs
cache_dir: .generated/jekyll-cache
...
exclude:
    - build-jekyll.sh
    - CMakeLists.txt
    - Gemfile
    - Gemfile.lock

Strangely enough, no .generated/jekyll-cache is created. Also no .jekyll-cache before the above change for that matter. From the generated .gitignore I understand that it might generate:

.sass-cache
.jekyll-cache
.jekyll-metadata

I want to change the path of all of those to either outside the source tree (into my build directory at /home/carlo/projects/aicxx/linuxviewer/linuxviewer-objdir) or if that is not possible, and for some reason it isn’t for the cache, into .generated/something).

4

those 2 paths both have a gens folder and I think that is an issue - but not positive.

Sounds like you got it to work - GPT is an interesting option.

Not sure about changing the path to those files.

5

I am pretty sure that is normal. Certain packages are installed with pacman or yay (from the AUR) and those end up in /usr/lib/ruby/gems/3.0.0/gems. It tried to reinstall everything however and then discovered that:

/usr/lib/ruby/gems/3.0.0/gems/webrick-1.7.0
/usr/lib/ruby/gems/3.0.0/gems/minima-2.5.1
/usr/lib/ruby/gems/3.0.0/gems/jekyll-feed-0.16.0
/usr/lib/ruby/gems/3.0.0/gems/jekyll-seo-tag-2.8.0

where not owned by any package, which prompted me to delete them (assuming a reinstall of jekyll would reinstall if needed). That, however, did not happen.
Moreover, when running bundle install after reinstalling, I got the error:
Bundler::GemNotFound: Could not find jekyll-seo-tag-2.8.0.gem for installation
and had to manually install that gem. After which I got:
Bundler::GemNotFound: Could not find minima-2.5.1.gem for installation
Which I also had to install manually before thing started to work again.
This looks like the webrick thing: as if jekyll-seo-tag and minima are no longer included with jekyll 3.0.0, but they were never cleaned up and still on my harddisk? In the end I installed them both using yay:

yay --rebuildall ruby-jekyll-seo-tag ruby-minima
