Ruby (Windows) を使用してプロジェクトを開始したところです。「rails server」を実行すると、次の ince ,essage が表示されます。

確かに私は何かを逃しています。ここに私の Gemfile があります: source ' https://rubygems.org '

gem 'rails', '3.2.13'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'bundler'
gem 'sqlite3'
gem 'mysql'
gem 'geocode'
gem 'gmaps4rails'
gem 'railties'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# 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'

まだ始めたばかりなので、Ruby コード ファイルはありません (または、新しい rail プロジェクトを作成したときに生成されるものを持っています)。

前もって感謝します、

迅速な回答をありがとうございますが、残念ながら同じ種類のエラーが発生しています:

sqlite3gem とgemの両方を含めないでくださいmysql。

  1. 既存のGemfile.lockファイルを削除します。

  2. 削除するgem 'sqlite3'

  3. gem 'mysql'と置き換えますgem 'mysql2', '~> 0.3.11'

  4. 実行bundle installして再試行してください。

また、システムに mysql がインストールされていることを確認してください。そして、config/database.ymlmysqlアダプタを使用するように構成しますdevelopment

編集: from (MySQL のバージョンなどに応じてそこに存在する必要があります) を に
コピーします。libmysql.dllC:\Program Files\MySQL\MySQL version\binC:/RailsInstaller/Ruby1.9.3/bin
