add the gem to your Jekyll configuration

[change2hao]

when I add the gem to my Jekyll configuration,and running jekyll build the console show errror: Configuration file: /Users/tianliwei/blog/_config.yml jekyll 2.5.3 | Error: undefined methodeach' for "-octopress-genesis-theme":String`

Thanks for the report. This is very much still a work in progress.

@change2hao Make sure your gem declaration in _config.yml is an array:

gems: [octopress-genesis-theme]

or simply

gems:
- octopress-genesis-theme

If that doesn't fix it, please re-run jekyll build --trace and paste the output.

@parkr I declaration

gems:
  -octopress-genesis-theme

and follow your advice, i changed to

gems:
- octopress-genesis-theme

and the trace as follows:

and i have installed octopress-genesis-theme use gem install octopress-genesis-theme

[ludwick]

The rb file in the installed gem is actually just octopress-genesis.rb in my installation:

find /Users/rachael/.rvm/gems/ruby-2.2.0/gems/octopress-genesis-theme-0.0.3/lib
/Users/rachael/.rvm/gems/ruby-2.2.0/gems/octopress-genesis-theme-0.0.3/lib
/Users/rachael/.rvm/gems/ruby-2.2.0/gems/octopress-genesis-theme-0.0.3/lib/octopress-genesis
/Users/rachael/.rvm/gems/ruby-2.2.0/gems/octopress-genesis-theme-0.0.3/lib/octopress-genesis/category-generator.rb
/Users/rachael/.rvm/gems/ruby-2.2.0/gems/octopress-genesis-theme-0.0.3/lib/octopress-genesis/version.rb
/Users/rachael/.rvm/gems/ruby-2.2.0/gems/octopress-genesis-theme-0.0.3/lib/octopress-genesis.rb

If I change _config.yaml to mention:

gems: [octopress-genesis]

It gets passed this.

[ludwick]

But, if I just use latest in github (see here for how) then it has the right name.

It's octopress-genesis-theme. I've updated the readme. Thanks.
