Heroku gemfile在尝试在本地打开和编辑我的网站时出错

我在使用我的在线课程中的教程构建了一个使用Heroku的网站。Heroku gemfile在尝试在本地打开和编辑我的网站时出错

Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 'sqlite3'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

这里是我的Gemfile：

source 'https://rubygems.org' 


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.2.5' 
# 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/rails/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. Read more: https://github.com/rails/turbolinks 
gem 'turbolinks' 
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder 
gem 'jbuilder', '~> 2.0' 
# bundle exec rake doc:rails generates the API under doc/api. 
gem 'sdoc', '~> 0.4.0', group: :doc 

# Use ActiveModel has_secure_password 
# gem 'bcrypt', '~> 3.1.7' 

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

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

group :development, :test do 
    # Call 'byebug' anywhere in the code to stop execution and get a debugger console 
    gem 'byebug' 
    gem 'sqlite3' 
end 

group :development do 
    # Access an IRB console on exception pages or by using <%= console %> in views 
    gem 'web-console', '~> 2.0' 

    # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring 
    gem 'spring' 
end 

group :production do 
    gem 'rails_12factor' 
    gem 'pg' 
end

这是一个完整的宝石:: LoadError：

require path_to_adapter 
rescue Gem::LoadError => e 
raise Gem::LoadError, "Specified '#{spec[:adapter]}' for database adapter, but the gem is not loaded. Add `gem '#{e.name}'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord)." 
rescue LoadError => e 
raise LoadError, "Could not load '#{path_to_adapter}'. Make sure that the adapter in config/database.yml is valid. If you use an adapter other than 'mysql', 'mysql2', 'postgresql' or 'sqlite3' add the necessary adapter gem to the Gemfile.", e.backtrace 
      end

您不能在Heroku上使用SQLite。请参阅https://simonecarletti.com/blog/2016/01/post-heroku-sqlite/ https://devcenter.heroku.com/articles/getting-started-with-rails4#write-your-app http：// stackoverflow.com/a/3897593/123527 –

切换到PostgreSQL试图在本地打开它时，我不断收到此错误。 SQLite不受支持。
