こんにちは、私はこの男のような同じ問題を抱えています: Ruby Guard の質問 - 'sqlite3 アダプターをインストールしてください' - railstutorial.org

「bundle exec rspec spec/requests/static_pages_spec.rb」を実行すると、次のようになります。

C:\Users\Me\Ruby\sample_app>bundle exec rspec spec/requests/static_pages_spec

しかし、私の database.yml は次のようになります。

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: postgresql
  host: localhost
  username: user
  database: app-dev

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: sqlite3
  database: db/production.sqlite3
  pool: 5
  timeout: 5000

ここで何を変更する必要がありますか? または、私が見ることができない別の問題がありますか？

PS: postgreSQL をインストールしたので、database.yml の開発パッセージを変更しました。そして、gemfile は次のようになります。

source 'https://rubygems.org'

gem 'rails', '3.2.11'
gem 'pg', '0.12.2'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test do
  gem 'rspec-rails', '2.11.0'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.5'
  gem 'coffee-rails', '~> 3.2.2'
  gem 'uglifier', '>= 1.2.3'
end

gem 'jquery-rails'

group :test do
  gem 'capybara', '1.1.2'
end

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

の現在の構成では、 &が使用している間config/database.yml、開発環境がオンになっています。また、 に含まれる宝石はありません。したがって、についてのエラーメッセージ。postgrestestproductionsqlite3sqlite3GemfilePlease install the sqlite3 adapter

postgresだけでなく、すべての環境で使用してみませんdevelopmentか?

のセクションtestとproduction同様のセクションを適切なデータベース名で作成します - development& database: app-prod` それぞれ。config/database.ymldatabase: app-test

sqlite3または、特定の環境で使用する場合はsqlite3、その環境用の gem のみを含めpg、他の環境用の gem を含めます。

Gemfile 構成の例:

以下の構成には、の場合のみのgem と&環境の場合のみのpggemが含まれます。productionsqlite3developmenttest

group :development, :test do
  gem 'sqlite3-ruby', :require => 'sqlite3'
