Question

Когда я запускаю мой сервер рельсы на терминале, я получаю следующее сообщение:

Вот моя Gemfile:

source 'https://rubygems.org' 
ruby '2.2.1'  

gem 'rails', '~> 4.2.5' 
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 'devise', '~> 3.5.3' 



group :development, :test do 
gem 'sqlite3' 
end 

group :production do 
gem 'pg' 
gem 'rails_12factor' 
end 



gem 'sdoc', '~> 0.4.0', group: :doc 
group :development, :test do 
gem 'byebug' 
end 
group :development do 
gem 'web-console', '~> 2.0' 
gem 'spring' 
end 

gem 'bootstrap-sass' 

Любая помощь с этим было бы гораздо оценили! Благодаря!

Answer 1

Вам нужно запустить команду

rails generate devise:install 

Answer 2

Вы должны сделать это в консоли

bundle install 

Тогда

bundle exec rails generate devise:install 
bundle exec rails generate device model_name 

в вашем случае model_name может быть Install

Answer 3

Сначала вы должны связать свои драгоценные камни:

bundle install 

Затем вы должны установить DEViSE:

rails g devise:install 

И тогда вы должны перезагрузить сервер рельсы:

Ctrl + C 
$ rails s
