请帮我解决我的问题 我已经阅读了这里的所有主题，但仍然无法理解发生了什么
所以我运行 git push heroku master
这是我得到的
rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.)
之后我更新了我的 Gemfile，就在这里
ruby '1.9.3'
source 'https://rubygems.org'
gem 'rails', '3.2.13'
gem 'mysql2'
gem 'pg'
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem 'therubyracer', :platform => :ruby
end
gem 'less-rails', '~> 2.2.6'
gem 'sass-rails', '~> 3.2.3'
gem 'twitter-bootstrap-rails', '2.2.4'
gem 'jquery-rails'
gem 'devise'
gem 'haml', '~> 4.0.0'
gem 'haml-rails'
gem 'cancan'
gem 'rails-i18n', '~> 3.0.0.pre'
gem 'i18n-js', :github => 'fnando/i18n-js'
gem 'obscenity'
gem 'thin'
gem 'will_paginate-bootstrap'
gem 'nifty-generators', :group => :development
gem 'rails_12factor'
gem 'mocha', :group => :test
之后 bundle install 显示错误
这里是 config/database.yml
production:
adapter: mysql2
host: 127.0.0.1
encoding: utf8
reconnect: false
database: xxx_production
pool: 5
username: root
password: "xxxx"
socket: /var/run/mysqld/mysqld.sock
development:
adapter: mysql2
host: localhost
encoding: utf8
reconnect: false
database: xxx_development
pool: 5
username: root
password: "xxxx"
socket: /var/run/mysqld/mysqld.sock
test:
adapter: mysql2
host: localhost
