Rails 5にアップグレードしようとすると、「Bundlerはgem "railties"と互換性のあるバージョンを見つけることができませんでした」というエラーが発生します

Rails 5.にアップグレードしようとしています。Gemfile.lockファイルを削除し、Gemfileを次のように編集しました。

source 'https://rubygems.org'


# Bundle Edge Rails instead: gem 'Rails', github: 'Rails/rails'
gem 'Rails', '5.0.0'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-Rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-Rails', '~> 4.1.0'
# See https://github.com/Rails/execjs#readme for more supported runtimes

group :development do

end

「バンドルインストール」を実行しましたが、以下のエラーが発生しました

$ bundle install
Your Gemfile lists the gem jquery-Rails (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.

    jquery-modal-Rails was resolved to 0.0.1, which depends on
      railties (< 5.0, >= 3.2.0)

    jquery-Rails was resolved to 4.1.1, which depends on
      railties (>= 4.2.0)

    Rails (= 5.0.0) was resolved to 5.0.0, which depends on
      railties (= 5.0.0)

    sass-Rails (~> 5.0) was resolved to 5.0.6, which depends on
      railties (< 6, >= 4.0.0)

    web-console (~> 2.0) was resolved to 2.3.0, which depends on

Rails 5にアップグレードできるように、Gemfileを適切に編集するにはどうすればよいですか？

繰り返されるjquery-Railsgemの1つを削除して、bundleinstallを再度実行してみてください。

// remove this line    
gem 'jquery-Rails'

また、これのためにあなたの宝石の「コーヒー-レール」ラインを変更してください：

gem 'coffee-Rails', '~> 4.2'

次のGemfileで問題なく実行されているRails 5プロジェクトがあります：
