Rails 4 - Gem::LoadError: Specified 'mysql2' for database adapter, but the gem is not loaded

Question

In my gemfile I have:

gem \'mysql2\'

My database.yml is as follows:

default: &default
  adapter: mysql2
  database: <         


        

Answer 1

try this:

bundle update mysql2

this command will update your 'mysql2' gem to the latest version (should be 0.3.17 or higher) and start your rails server.
