Ruby on rails 在ruby on rails上实现postgresql时出错

我在实现rake数据库时遇到以下错误：migrate

rake aborted!
Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.)

我使用postgresql在数据库中创建了两个表

我的database.yml是

development:
  adapter: postgresql
  encoding: unicode
  host: localhost
  database: shop_development
  pool: 5
  username: postgres
  password: 

test:
  adapter: postgresql
  encoding: unicode
  host: localhost
  database: shop_test
  pool: 5
  username: postgres
  password: 

production:
  adapter: postgresql
  encoding: unicode
  host: localhost
  database: shop_production
  pool: 5
  username: postgres
  password: 

我还运行了以下命令：

C:\Sites\shop>gem install 'pg'
Successfully installed pg-0.14.1-x86-mingw32
1 gem installed
Installing ri documentation for pg-0.14.1-x86-mingw32...
Installing RDoc documentation for pg-0.14.1-x86-mingw32...

但这仍然给了我同样的错误

我的文件包含以下内容：

您是否已运行

捆绑安装
？

看起来当前安装了
sqlite3
，但
pg
没有

如果要将数据从
sqlite3
移动到
pg
，请查看此railscast:
请尝试使用此

 sudo apt-get install postgresql postgresql-client postgresql-contriblibpq-dev

你能把你的Gemfile添加到问题中吗？@jvnill我已经编辑了这个问题。你能帮我修改一下我的Gemfile.lock吗。Gemfile比较干净，所以你可以用它来代替吗？嗨，Prathamesh，我已经清理了你的一些代码格式，但是请看一下格式指南，它会让你的问题更容易阅读：我的Gemfile有以下内容：-源代码“gem”rails、“3.2.11”#而不是Bundle edge rails:#gem“rails”，：git=>'git://github.com/rails/rails.git“gem”sqlite3“#默认情况下，gem仅用于资产，在生产环境中不需要。组：资产做gem'sass-rails'，“~>3.2.3”gem'coffee-rails'，“~>3.2.1”#有关更多支持的运行时gem'uglifier'，“>=1.0.3”end-gem'jquery-rails'是的，我已运行bundle安装C:\Sites\shop>bundle安装。。。您的包已完成！使用
bundle show[gemname]
查看捆绑gem的安装位置。如何从ruby on rails命令启动postgresql控制台promptI可以在gem文件中查看gem，但不在您发布的已安装宝石列表中。@mind.blank我已经用已安装宝石列表编辑了我的问题，请告诉我是否有需要添加的宝石。不确定。顺便问一下，为什么您的数据库都在开发？@vijikumar谢谢，现在它正在工作。您能告诉我如何在ruby on rail中启动postgresql控制台吗？您能指定命令吗
