Rails 4 にアップグレードすると、次のエラーが発生します。
Bundler could not find compatible versions for gem "railties":
In Gemfile:
rails (= 4.0.0) ruby depends on
railties (= 4.0.0) ruby
sass-rails (~> 4.0.0) ruby depends on
railties (4.0.0.rc2)
私の Gemfile は次のようになります。
source 'https://rubygems.org'
ruby '2.0.0'
gem 'rails', '4.0.0'
gem 'sass-rails', '~> 4.0.0'
gem 'coffee-rails', '~> 4.0.0'
# Other gems
どんな助けでも大歓迎です。
