error undefined method `output=' when running test

[worrawutp]

I require 'minitest/colorize' in my test file and run it with rake and I got following error message.
Note that I use minitest 5.4.2 and minitest-colorize 0.0.5

rake spec
C:/Ruby200/lib/ruby/gems/2.0.0/gems/minitest-colorize-0.0.5/lib/minitest/colorize.rb:88:in <top (required)>': undefined methodoutput=' for Minitest::Unit:Class (NoMethodError)
