Невозможно решить проблему зависимости от ROR

Question

Я довольно новичок в этом ROR приложении, поэтому, пожалуйста, поймите, если мои формулировки для описания моей проблемы не так точны.

Я сейчас пытаюсь повторить то, что делает приведенный ниже github.

https://github.com/harrystech/prelaunchr

Я разбираюсь с частью установки разработчика, но когда я выполняю

bundle exec rake db:migrate

, результат в моей команде:

Traceback (последний последний вызов): 20: из /home/leesungyong/.rbenv/versions/2.5.3/bin/rake:23:in <main>' 19: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems.rb:309:in activ_bin_path '18: из / home / leesungyong /.rbenv / версии / 2.5.3 / lib / ruby ​​/ 2.5.0 / rubygems.rb: 309: в synchronize' 17: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems.rb:311:in блоке в activ_bin_path '16: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby / 2.5.0 / rubygems.rb: 243: в finish_resolve' 15: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/request_set.rb:397:in resol_current '14: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/request_set.rb:385: в resolve' 13: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver.rb:188:in разрешить '12: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo/lib/molinillo/resolver.rb:42:in resolve' 11: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo/lib/molinillo/resolution.rb:64:in решите '10: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo/lib/molinillo/resolution.rb:106:in start_resolution' 9: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo/lib/molinillo/resolution.rb:165:in initial_state'8: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo / lib / molinillo / Delegates /pecification_provider.rb: 51: в sort_dependencies' 7: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo/lib/molinillo/delegates/specification_provider.rb:69:in with_no_such_dependency_error_handling '6: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver/molinillo/lib/molinillo/delegates/specification_provider.rb:52:in block in sort_dependencies' 5: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver.rb:277:in sort_dependencies '4: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver.rb:277: в with_index' 3: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver.rb:277:in sort_by '2: из /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver.rb:277:in each' 1: from /home/leesungyong/.rbenv/versions/2.5.3/lib/ruby/2.5.0/rubygems/resolver.rb:283:in блок в sort_dependencies' /home / leesungyong / .rbenv / версии / 2.5.3 / lib / ruby ​​/ 2.5.0 / rubygems / resolver.rb: 231: в `search_for ': невозможно разрешить зависимость: пользователь запросил' did_you_mean (= 1.2.0) '(Gem :: UnsatisfiableDependencyError)

Кстати, я использую Ubuntu ..

Хорошо, у меня был некоторый прогресс в ошибке.Я обнаружил, что может быть ошибка версии с моим упаковщиком, и что я должен использовать bundler -v 1.15.0.pre.3 .Итак, я сделал следующее, но на этот раз, когда я

bundle exec rake db:create

вывод

could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting
    TCP/IP connections on port 5432?
