Мне пришлось сначала изменить свой Gemfile (я удалил комментарии, чтобы сделать текст короче):
source 'https://rubygems.org'
gem 'rails', '4.2.0'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring'
end
в
source 'https://rubygems.org'
gem 'rails', '4.2.0'
gem 'sass-rails', '5.0.1'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '2.2.3'
gem 'sdoc', '0.4.0', group: :doc
group :development, :test do
gem 'sqlite3', '1.3.9'
gem 'byebug', '3.4.0'
gem 'web-console', '2.0.0.beta3'
gem 'spring', '1.1.3'
end
теперь, когда я пытаюсь запустить сервер rails с rails server -b $IP -p $PORT
, я получаю следующее сообщение об ошибке:

Я попробовал запустить серверы перед изменением Gemfile, и он работает, поэтому это должно быть из-за новых изменений. Также я знаю об ошибке, которую он говорит ruby-2.1.5
, и в моем Gemfile я поставил 4.2.0, но я не знаю, как это изменить, или если это даже проблема? я попытался добавить ruby '2.1.5'
в исходную строку, ничего не изменилось. Также я изменил 'rails', '4.2.0'
на 2.1.5, но потом обновление не сообщило мне Could not find gem 'rails (= 2.1.5) ruby' in the gems available on this machine.
