Could not find mime-types-2.4.3 in any of the sources 
Run `bundle install` to install missing gems. 

Hier ist der gemfile (der Standard eines w meine Rails 4.2 erstellt):

source 'https://rubygems.org' 


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.2.0' 
# 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/sstephenson/execjs#readme for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# Use jquery as the JavaScript library

# bundle exec rake doc:rails generates the API under doc/api. 
gem 'sdoc', '~> 0.4.0', group: :doc 

# Use ActiveModel has_secure_password 
# gem 'bcrypt', '~> 3.1.7' 

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

# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 

group :development, :test do 
    # Access an IRB console on exception pages or by using <%= console %> in views 
    gem 'web-console', '~> 2.0' 

    # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring 
    gem 'spring' 
end 

Hinweis - Mime-Typ 2.4.3 im Gemfile.lock befindet
