Jekyll 3.0.0.beta1 - jekyll/deprecator (LoadError)

[kaatt]

My Jekyll site uses jekyll-redirect-from gem and a couple others. Simply installing v3.0.0.beta1 and running jekyll b didn't work:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb:2007:in `raise_if_conflicts': Unable to activate jekyll-redirect-from-0.6.2, because jekyll-3.0.0.pre.beta1 conflicts with jekyll (~> 2.0) (Gem::LoadError)

Thanks to @envygeeks in #3324, I forked the gems, edited the .gemspec file and commented out the s.add_dependency "jekyll" line.

Now running any jekyll command gives me this:

fatal: Not a git repository (or any of the parent directories): .git
/Library/Ruby/Gems/2.0.0/gems/jekyll-3.0.0.pre.beta1/bin/jekyll:15:in <top (required)>': cannot load such file -- jekyll/deprecator (LoadError) from /usr/bin/jekyll:23:inload'
from /usr/bin/jekyll:23:in `

'

Everything works if I don't put the lines in _config.yml to use extra gems.

If you have a Gemfile, run bundle exec jekyll build. Using bundle exec is highly recommended.

Thanks, I fixed this by adding gem 'jekyll', '3.0.0.pre.beta1' to my Gemfile.
