我使用标准配置（SQLite 3）开发了我的应用程序。我想在heroku上部署并且必须更改为postgresql。

但是当我尝试迁移我的 db-schema 时出现此错误。

rake db:migrate
rake aborted!
/Users/adrianschnell/Sites/bills_cmd/config/initializers/session_store.rb:3: syntax error, unexpected ':', expecting $end
...sion_store :cookie_store, key: '_bills_cmd_session'

我不知道我现在要做什么。我的 Gem 文件包含 'pg' 并且我的 database.yml 看起来像：

# PostgreSQL v0.8.x
#   gem install pg
development:
  adapter: postgresql
  encoding: unicode
  database: bills_cmd_dev
  pool: 5
  username: adrianschnell
  password:
  # 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: postgresql
  encoding: unicode
  database: bills_cmd_test
  pool: 5
  username: adrianschnell
  password:

PostgreSQL 正在运行 - 通过终端我可以访问它。

编辑：我注意到，在尝试创建 postgre 数据库时出现以下错误：

rake db:create:all
rake aborted!
syntax error on line 18, col 11: `'
/Library/Ruby/Gems/1.8/gems/railties-3.2.11/lib/rails/application/configuration.rb:115:in `database_configuration'

Tasks: TOP => db:create:all => db:load_config
(See full trace by running task with --trace)

经过数小时的搜索和测试不同的建议，我在这里尝试了这些建议：stackoverflow

尤其是Darren的加入是我的解决方案。现在我的 RoR 应用程序正在运行 postgre。
