Error: mime-types-data requires Ruby version >= 2.0 -

i install clean ubuntu14.04 virtual machine in vware fusion , updated it. trying install mime-tyes-data

sudo gem install mime-types-data -v 3.2015.1120

the error shows

error: error installing mime-types-data: mime-types-data requires ruby version >= 2.0.

before update ruby version by

sudo apt-get install ruby2.0

sudo ln -sf /usr/bin/ruby2.0 /usr/bin/ruby

it seems version of ruby 2.0 already, error still exists.

i facing same problem trying install rails sudo. getting: error: error installing mime-types-data: mime-types-data requires ruby version >= 2.0.

the thing ruby -v gives me ruby 2.2.1p85 while sudo ruby -v gives me ruby 1.9.3p484, instead of sudo gem install rails did gem install rails , worked.

that found solution: https://github.com/jekyll/jekyll/issues/3558

hope helps.
