mime-types requires 'json' but it is not in the dependencies

[joekhoobyar]

Line 4 in mime/type.rb is: require 'json'
This should be added to the gem's dependencies.

No. The Ruby standard library includes JSON as of sometime in Ruby 1.9.x, which means that I can always assume that it's there in a sane environment. The installation of the json gem is completely unnecessary, and json-pure does not work with mime-types.

If you're using mime-types on Rubinius, it's up to you to make sure the Ruby standard library is present. My position on this will change if and when MRI stops including JSON.
