`require': cannot load such file -- bundler (LoadError)

Question

I was following up from https://jekyllrb.com/docs/installation/ to install Jekyll and I have made sure that I have Xcode command line tools, gcc and make installed. Version of ruby is 2.1.1 I have installed Jekyll using

gem install jekyll

I got following success message

  Done installing documentation for safe_yaml, rouge, forwardable-extended, pathutil, mercenary, liquid, kramdown, ffi, rb-inotify, rb-fsevent, listen, jekyll-watch, sass-listen, sass, jekyll-sass-converter, colorator, public_suffix, addressable, jekyll after 14 seconds
        19 gems installed

But when I execute jekyll --version

I got following error

Answer 1

Error was solved by installing new version of bundler again, I had installed it previously as well but there was version issue

gem install bundler

Check your bundler version by

bundler --version

If everything is fine it will show version # Then again run jekyll --version and everything should go fine
