Rails server does not start - Could not find gem error

Question

When I run the rails s command from my terminal (Mac OSX Yosemite), I get the following error:

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

When I start the installation of the package, I get "Using mime-types 2.4.3"

 Using rake 10.4.2 Using i18n 0.7.0 Using json 1.8.2 Using minitest 5.5.1 Using thread_safe 0.3.4 Using tzinfo 1.2.2 Using activesupport 4.2.0 Using builder 3.2.2 Using erubis 2.7.0 Using mini_portile 0.6.2 Using nokogiri 1.6.6.2 Using rails-deprecated_sanitizer 1.0.3 Using rails-dom-testing 1.0.5 Using loofah 2.0.1 Using rails-html-sanitizer 1.0.1 Using actionview 4.2.0 Using rack 1.6.0 Using rack-test 0.6.3 Using actionpack 4.2.0 Using globalid 0.3.3 Using activejob 4.2.0 Using mime-types 2.4.3 Using mail 2.6.3 Using actionmailer 4.2.0 Using activemodel 4.2.0 Using arel 6.0.0 Using activerecord 4.2.0 Using debug_inspector 0.0.2 Using binding_of_caller 0.7.2 Using coffee-script-source 1.9.1 Using execjs 2.3.0 Using coffee-script 2.3.0 Using thor 0.19.1 Using railties 4.2.0 Using coffee-rails 4.1.0 Using hike 1.2.3 Using multi_json 1.10.1 Using jbuilder 2.2.8 Using jquery-rails 4.0.3 Using bundler 1.7.12 Using tilt 1.4.1 Using sprockets 2.12.3 Using sprockets-rails 2.2.4 Using rails 4.2.0 Using rdoc 4.2.0 Using sass 3.4.12 Using sass-rails 5.0.1 Using sdoc 0.4.1 Using spring 1.3.2 Using sqlite3 1.3.10 Using turbolinks 2.5.3 Using uglifier 2.7.0 Using web-console 2.0.0 

But running the "rails s" command again results in the same error message:

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

Here's the gemfile (my Rails 4.2 was created by default):

 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 gem 'jquery-rails' # Turbolinks makes following links in your web application faster.

Note. mime-types 2.4.3 is located in the Gemfile.lock file

Any ideas on what might be the issue?

Thank you for your time.

Answer 1

try installing the --path vendor / cache package

Try

 bundle update mime-types 

then start the server again.
