jekyll vs bundle exec jekyll

[sr-murthy]

Hi

THis is more of a question rather an issue (I am using bundle exec jekyll <command> as per the GitHub pages instructions) but what does bundler do in relation to jekyll, and what is the difference between, say, jekyll [build | serve] vs bundle exec jekyll [build | serve]?

Right now I am able to build and serve the site locally with bundle exec jekyll [build | serve], but when I jekyll [build | serve] it throws the following error

/Library/Ruby/Gems/2.0.0/gems/safe_yaml-1.0.4/lib/safe_yaml/psych_resolver.rb:4:in `<class:PsychResolver>': uninitialized constant Psych::Nodes (NameError)
