Latest version of Jekyll (3.8.3) not compatible with latest github-pages gem (188) - Depends on Jekyll (= 3.7.3)

[simon-spenc]

Before submitting an issue, please be sure to

• Read the contributing instructions
• Update to the latest Gem version (run bundle update github-pages)

This issue affects

• [] The site generated by GitHub Pages
• Building sites locally

The GitHub Pages Gem is intended to help users replicate the GitHub Pages build environment locally. If your issue affects both the hosted version and the version previewed locally, you may be better suited reporting seeking support in other forums.

What did you do (e.g., steps to reproduce)

• I believe this issue is the same, but I wasn't sure: update to Jekyll 3.8 #555

Following the Jekyll & Github Pages instructions (with no additional gems or code) I added gem 'github-pages' , group: :jekyll_plugins' to my gem file. And then got this error after running bundle update:

Bundler could not find compatible versions for gem "jekyll":
  In Gemfile:
    github-pages was resolved to 4, which depends on
      jekyll (= 1.1.2)

    jekyll-feed (~> 0.6) was resolved to 0.10.0, which depends on
      jekyll (~> 3.3)

I then tried updating the gem file to specify the latest version of Github Pages by adding gem 'github-pages' ,'188', group: :jekyll_plugins' to the gem file and got this error:

Bundler could not find compatible versions for gem "jekyll":
  In Gemfile:
    jekyll (~> 3.8.3)

    github-pages (= 188) was resolved to 188, which depends on
      jekyll (= 3.7.3)

It seems like the version of Jekyll that I'm running (latest as I just installed Jekyll yesterday) not the right version or requires an earlier version for githup-pages gem.

What did you expect to happen?

bundle install to resolve successfully

What happened instead?

Got an error:

Bundler could not find compatible versions for gem "jekyll":
  In Gemfile:
    jekyll (~> 3.8.3)

    github-pages (= 188) was resolved to 188, which depends on
      jekyll (= 3.7.3)

GitHub Pages hasn't updated to use Jekyll 3.8.3 yet. You'll be able to work with both gems by downgrading Jekyll in your Gemfile to 3.7.3.

Thanks Matt - I'll close this ticket for now.

@simon-spenc please upvote and comment on #555. It will help draw attention to it and get it updated sooner

After spent couple of hours did research on this issue, I got the solution. I took time to spent on reading the Gemfile and understood what was mentioned there. This was the error encountered:

Bundler could not find compatible versions for gem "jekyll":
  In Gemfile:
    github-pages was resolved to 4, which depends on
      jekyll (= 1.1.2)

    jekyll-feed (~> 0.6) was resolved to 0.12.1, which depends on
      jekyll (>= 3.7, < 5.0)

code from Gemfile:

source "https://rubygems.org"
  
# Hello! This is where you manage which Jekyll version is used to run.
# When you want to use a different version, change it below, save the
# file and run `bundle install`. Run Jekyll with `bundle exec`, like so:
#
#     bundle exec jekyll serve
#
# **This will help ensure the proper Jekyll version is running.**
# Happy Jekylling!
gem "jekyll", "~> 3.8.5"

# This is the default theme for new Jekyll sites. You may change this to anything you like.
gem "minima", "~> 2.0"

# If you want to use GitHub Pages, remove the "gem "jekyll"" above and
# uncomment the line below. To upgrade, run `bundle update github-pages`.
gem 'github-pages', group: :jekyll_plugins

so I just commented below line:
#gem 'github-pages', group: :jekyll_plugins

and let the bundle to fetch:
gem "jekyll", "~> 3.8.5"

then run this command:
bundle install

Issue resolved for me.

$ bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

@joshuaspy it doesn't look like your solution installs the github-pages gem at all (since you commented it out in the Gemfile)

I think we just have to wait until the github-pages gem is updated (strange it hasn't yet)... #555

BTW using jekyll 3.7.4 is all good with the newest github-pages gem

@joshuaspy did you have this error?

$ bundle
Fetching gem metadata from https://rubygems.org/..........
Fetching gem metadata from https://rubygems.org/.
You have requested:
  jekyll ~> 3.8.5

The bundle currently has jekyll locked at 4.0.0.
Try running `bundle update jekyll`

If you are updating multiple gems in your Gemfile at once,
try passing them all to `bundle update`
