Installing themes requires install of outdated gems?

Help
1

hi jekyll land,

i’m new to jekyll (and ruby), i’ve set it up locally on a debian machine to build a website that i’ll then push to a vps.

the problems i keep encountering is that after i download a theme (eg a zip from github) to set up my site, they often have dependency problems and wont run. i often get messages like this when i try to run bundle install in the theme dir:

"Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (~> 1.15)

  Current Bundler version:
    bundler (2.0.2)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (~> 1.15)' in any of the relevant sources:
  the local ruby installation"

and if i eg install the older bundler, then i end up with tons of duplicated gems, because the older versions are also added.

i had this happen on a few older themes so i thought they were broken, but then i just tried with the textlog theme which is not very old (https://github.com/heiswayi/textlog). it also happened with the hack-css theme. the gemfile.lock of hack-css declares that it was bundled with bundler 1.13.x. does that mean that the only way to use that theme is to downgrade bundler (+all dependencies)?

it’s got me thinking that it’s me going about things the wrong way. i’m able to set up a site correctly with the minima and jekyll-now and minimal-mistakes themes, by following the jekyll tutorials. but i didn’t want to go with any of those.

and if different themes require different versions of lots of gems, it seems like it would make changing themes a difficult business.

if anyone can enlighten me a little about any of this, i’d be grateful.

thx.

It is a pity that nobody has picked this up. I am new to Jekyll and ruby and tonight runs onto the same boat as yours. I am also wondering how does the Jekyll theme dev work? If for using a older theme runs with older gem packages I will have to downgrade the whole environment to be like that, I so do not understand this.
This is 2021, if anyone experienced picks this up please let us have a clue. Many thanks.

Keep using Bundler 2

Rather delete Gemfile.lock which is the thing that sets the Bundler 1 version

And then when you do Bundler install you’ll get a new lockfile

Thanks let me try that tonight to see how it goes. Another thing is I saw that the original package was built with Jekyll 3.0.* not 4.2 which I’m having now. I will let you guys know about the outcomes.

Many thanks for watching guys. I am using this theme East by Aspire Themes

The make it running,

  1. delete Gemfile.lock

try


bundle install

get


Deprecation: You appear to have pagination turned on, but you haven't included the `jekyll-paginate` gem. Ensure you have `plugins: [jekyll-paginate]` in your configuration file.
  1. fix the deprecated pagination issue, will look into again in the future if it runs into further issue

2.1 add in _config.yml file with


# don't need to as the original config included this

gems:

- jekyll-paginate

paginate: 10

2.2 add in Gemfile file with


group :jekyll_plugins do

gem "jekyll-paginate"

end
  1. in Terminal try:

bundle install

got following. p.s. I am in a newly setup macOS on Apple Silicon


/Users/xxxxx/.gem/ruby/3.0.0/gems/jekyll-4.2.0/lib/jekyll/commands/serve/servlet.rb:3:in `require': cannot load such file -- webrick (LoadError)
  1. add webrick to bundle (in this theme build?)

bundle add webrick
  1. finally rebuild with success!

bundle install

bundle exec jekyll serve

Enjoy!

Now published on Github Pages: Revive old Jekyll theme to version 4.2 running on macOS Big Sur with Apple Silicon
