部署Rails应用程序到Heroku时的错误

Question

你好，我刚刚开始学习Ruby on Rails，并且正在观看Railstutoprials屏幕转换。然而，当我做我的git推到heroku并尝试加载我的rails应用程序时，我得到一个错误，我的日志看起来像这样。

我的Gemfile看起来像：

source 'https://rubygems.org' 

ruby '2.0.0' 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.0.0' 

# Use postgresql as the database for Active Record 
gem 'pg', group: :production 

gem 'sqlite3', group: [:test, :development] 

# Use V8 JavaScript engine 
gem 'therubyracer' 

# Use SCSS for stylesheets 
gem 'sass-rails', '~> 4.0.0' 

# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier', '>= 1.3.0' 

# Use CoffeeScript for .js.coffee assets and views 
gem 'coffee-rails', '~> 4.0.0' 

# Use jquery as the JavaScript library 
gem 'jquery-rails' 

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks 
gem 'turbolinks' 

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder 
gem 'jbuilder', '~> 1.2' 

gem 'rails_12factor' 

group :doc do 
    # bundle exec rake doc:rails generates the API under doc/api. 
    gem 'sdoc', require: false 
end 

# Use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

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

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

# Use debugger 
# gem 'debugger', group: [:development, :test] 

，最后我的database.yml

# SQLite version 3.x 
# gem install sqlite3 
# 
# Ensure the SQLite 3 gem is defined in your Gemfile 
# gem 'sqlite3' 
development: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    pool: 5 
    timeout: 5000 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake". 
# Do not set this db to the same as development or production. 
test: 
    adapter: sqlite3 
    database: db/test.sqlite3 
    pool: 5 
    timeout: 5000 

production: 
    adapter: postgresql 
    database: social_pantry 
    pool: 5 
    timeout: 5000
