From: Ja Tse Date: 2012-09-25T08:30:41+09:00 Subject: Unable to run cucumber Hi All I have just created a new cucumber test framework and this is what it looks like. ~/cucumber/cucumber_sinatra$> tree . ├── Gemfile ├── Gemfile.lock ├── features │   ├── fruit_list.feature │   ├── step_definitions │   └── support │   └── env.rb ├── lib │   └── fruit_app.rb └── spec 5 directories, 5 files And the gem file includes the folowing gems: source :rubygems gem 'sinatra' gem 'json' group :test do gem 'cucumber' gem 'rspec' gem 'rack-test' end And I have done, bundle install many times after deleting the old Gemfile.lock. And all looks OK. ~/cucumber/cucumber_sinatra$> bundle install Fetching source index for http://rubygems.org/ Using builder (3.1.3) Using diff-lcs (1.1.3) Using json (1.7.5) Using gherkin (2.11.2) Using cucumber (1.2.1) Using rack (1.4.1) Using rack-protection (1.2.0) Using rack-test (0.6.1) Using rspec-core (2.11.1) Using rspec-expectations (2.11.3) Using rspec-mocks (2.11.3) Using rspec (2.11.0) Using tilt (1.3.3) Using sinatra (1.3.3) Using bundler (1.0.15) Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. However if I try to run cucumber I get the following error. ~/cucumber/cucumber_sinatra$> bundle exec cucumber features/ Could not find builder-3.1.3 in any of the sources Run `bundle install` to install missing gems. -- Posted via http://www.ruby-forum.com/.
