gh-pages version and jekyll version problem

[DarkHollow]

I'm having a version problem when I do install or update. Instead of getting gh-pages 104 and jekyll 3.3.0, I'm getting 35/39 and 2.4.0

I do as follows

$ jekyll new darkhollow.github.io

And get

New jekyll site installed in /Users/roberto/Proyectos/darkhollow.github.io.

Using jekyll-feed 0.8.0
Bundle complete! 3 Gemfile dependencies, 21 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

And then

$ cd darkhollow.github.io/
$ vim Gemfile 

and I comment the line: gem "jekyll", "3.3.0" and I uncomment the line: gem "github-pages", group: :jekyll_plugins

Finally I do

$ bundle update

and I get this

Bundle updated!

So jekyll goes back to 2.4.0 version and github-pages to 35 version.

If I delete the Gemfile.lock and do bundle install it gets the same versions.

And if I serve I get an error, I do

$ bundle exec jekyll serve

and get

    Liquid Exception: Included file '_includes/icon-github.html' not found in about.md
jekyll 2.4.0 | Error:  Included file '_includes/icon-github.html' not found

I guess it's for the old versions I get when I do update

Last try, if I only write in the Gemfile source and the github pages gem, I get this versions

[csaid]

I believe I'm having the same issue. My Gemfile looks like this:

source 'https://rubygems.org'
gem 'github-pages', group: :jekyll_plugins

but when I bundle update github-pages it says "Using jekyll 2.4.0".

[bakercp]

Same issue here.

Same issue!

[DarkHollow]

I have found that in Gemfile if instead of

gem "github-pages", group: :jekyll_plugins

I tell to use specific version

gem "github-pages", "104"

apparently works fine if you bundle update or bundle install again, but of course, I don't think this is a fix.

[bakercp]

Thanks @DarkHollow I can confirm that when the contents of my Gemfile is

source 'https://rubygems.org'
gem 'github-pages', '104', group: :jekyll_plugins

I am then able to run bundle update and then bundle exec jekyll serve and I'm back in action.

Thanks!

[nickserv]

I also ran into this issue, including on Travis. It seems as if bundler is consistently installing the wrong version. Could it be that the version 39 is considered greater than 104 because they're being sorted alphabetically instead of numerically?

I'm using the following Gemfile as a temporary workaround:

source 'https://rubygems.org'
gem 'github-pages', '>=104', group: :jekyll_plugins

[sudopluto]

I am also having this issue.

[davidobrien1985]

I believe I'm seeing the same issue, although no idea how to fix it. I only really use Jekyll so that I can write markdown, don't really understand how Jekyll works.

I had a blog (www.david-obrien.net) that looked perfectly fine, pushed a new page, now it's broken. Reset the head to before I uploaded the commit, still broken. This leads me to believe that something in the underlying Jekyll or Github infra is broken.

How do I fix or troubleshoot this?

[DarkHollow]

@davidobrien1985 have you did bundle update after modifying the Gemfile?

Anyway, I see your blog it's using SSL but I think GitHub Pages not, so the browser is trying to get the css and js from https://yourgithub.github.io/... but GitHub doesn't give the files over SSL.

[nickserv]

@davidobrien1985 Are you deploying this with GitHub Pages or a custom Jekyll based system? It sounds like you may want to try the Gemfile code in my comment (along with @DarkHollow's comment).

[davidobrien1985]

@DarkHollow I just realised, the Gemfile doesn't change the Github behaviour, right? That's just for local jekyll serve builds? If the HTTPS thing is the issue then I don't know why now. This was always configured like this.

@nickmccurdy I'm using this with Github Pages.

[davidobrien1985]

Hmm, the HTTPS thing might have been it @DarkHollow . I always had url in _config.yml commented out and it always worked, until now. Brought it back in with https://www.david-obrien.net and my formatting is correct again. Thanks.

[nickserv]

@davidobrien1985 As far as I'm aware, GitHub Pages runs something like jekyll build --safe with the same versions of Ruby, Jekyll, and plugins used in this gem. Having a Gemfile won't affect GitHub Pages, you can't specify custom versions of gems.

[falsandtru]

I got the mostly same problem.

@falsandtru Expecify the Github pages gem version

source 'https://rubygems.org'
gem 'github-pages', '>=104', group: :jekyll_plugins

Use this as a temporary workaround.

[falsandtru]

I found the expected issue https://github.com/bundler/bundler/issues/5154. This is almost certainly a bug of bundler. A workaround is:

source 'https://rubygems.org'

gem 'github-pages'

[DarkHollow]

@falsandtru so if it's a bundler version issue I guess I'm going to close this issue.

[falsandtru]

I think so, we should go to that issue.

[jarrodu]

Same issue. :+1:

[benbalter]

This is related to https://github.com/bundler/bundler/issues/5154. For now you can use the following work around which @nickmccurdy pointed out:

source 'https://rubygems.org'
gem 'github-pages', '>=104', group: :jekyll_plugins

[nickserv]

Related PR: https://github.com/CocoaPods/Molinillo/pull/54

[nickserv]

This has been fixed upstream! Users of this gem should be fine now, though you might need to bundle update.

I'm assuming this issue can be closed, though the workaround should be removed from the readme.

Edit: I don't know why, but I'm still having this problem, even after bundle update.

[DirtyF]

@nickmccurdy Not yet as the issue is still present because even if the fix has been merged into master, we still need to wait for next bundler gem release.

[falsandtru]

Now I can install the latest gh-pages gem via bundle update with bundler 1.13.6. However, I need to run that command two times.

[nickserv]

Sweet, this now works for me on a clean bundle install after deleting Gemfile.lock!

[benbalter]

Based on @nickmccurdy and @falsandtru comments, I'm going to call this closed. Please follow their instructions if you are experiencing this issue.

[DarkHollow]

Alright, with the new version of bundler everything is going normally.

Thank you all for your help and dedication.

Closed.

[nickserv]

I'm having this issue again, but only when I'm using html-proofer in the same Gemfile like this.

source 'https://rubygems.org'

gem 'github-pages', group: :jekyll_plugins

@nickmccurdy Seems that html-proffer 3.8.0 bumped a lot of gems while github-pages has older versions.

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:
    github-pages (>= 176) was resolved to 176, which depends on
      activesupport (= 4.2.9)

    html-proofer (>= 3.8.0) was resolved to 3.8.0, which depends on
      activesupport (< 6.0, >= 4.2)

Bundler could not find compatible versions for gem "typhoeus":
  In Gemfile:
    github-pages (>= 176) was resolved to 176, which depends on
      github-pages-health-check (= 1.3.5) was resolved to 1.3.5, which depends on
        typhoeus (~> 0.7)

    html-proofer (>= 3.8.0) was resolved to 3.8.0, which depends on
      typhoeus (~> 1.3)

Seems like the following is a reasonable temporary solution.

gem 'github-pages', group: :jekyll_plugins
gem 'html-proofer', '~> 3.7.0'

I'm getting a varient of this issue. As at the top of this thread it's with the github-pages gem.

Blog nconroy$ bundle update
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`.

I am getting a similar error as well

    minima (~> 2.0) was resolved to 2.4.0, which depends on
      jekyll (~> 3.5)

To resolve this for now I altered my Jekyll version to 3.6.2 in my Gemfile and then specified:

gem "github-pages", 179, group: :jekyll_plugins

Having never used Jekyll or done much with Ruby Gems I just kept bumping that number up till it matched. Weird stuff.

In any case this seems like a pretty poor work around....
