Is test-unit incompatible with ruby 2.2.0? -

-

i'm new ruby. i'm starting play following this guide setting ruby, rvm, update mac current version, without problem. installed test-unit gem , try tdd script. running test nothing happen. run ruby "-d" option , happen.

exception 'loaderror' @ /users/blacksheep/.rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems.rb:1222 - cannot load such file -- rubygems/defaults/operating_system

exception 'loaderror' @ /users/blacksheep/.rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems.rb:1231 - cannot load such file -- rubygems/defaults/ruby

exception `loaderror' @ /users/blacksheep/.rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54 - cannot load such file -- test/unit

exception 'nomethoderror' @ /users/blacksheep/.rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems/specification.rb:1984 - undefined method 'to_ary' #

what problem?

versions:

  • ruby: 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]
  • rvm: 1.26.10
  • gem: 2.4.6

edit: i've downgrade version 2.0.0 , works fine. test-unit gem not made current ruby version?

up 2.1, ruby shipped test/unit, of 2.2, it's been removed.

it's still available gem: https://github.com/test-unit/test-unit/. readme: "test::unit 1.2.3 original test::unit, taken straight ruby distribution. being distributed gem allow tool builders use stand-alone package. (the test framework in ruby going radically change soon)."

if make sure test-unit gem install (either gem install test-unit or add gem 'test-unit' gemfile) should solve problem.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
