RailsでMySQL動かないときの対処法

動かない例

      invoke  active_record
/Users/thr3a/.rvm/gems/ruby-2.2.1/gems/activerecord-4.2.4/lib/active_record/connection_adapters/connection_specification.rb:177:in `rescue in spec': Specified 'mysql2' for database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). (Gem::LoadError)

いやgem "mysql2"入れてるからw

ただのバグっぽい

Gemfile.lock削除してGemfileで旧バージョンを指定してあげる

gem 'mysql2', '~> 0.3.20'

bundle installすればおk
