Question

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，我收到了这个错误。

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'，我的database.yml包含：

# 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 db时出现以下错误：

rake db:create:all
rake aborted!
syntax error on line 18, col 11: `'

(See full trace by running task with --trace)

经过数小时的搜索和测试不同的建议后，我尝试了这些建议：stackoverflow

尤其是Darren的输入对我来说是解决方案。现在我的RoR App正在运行postgre。

错误：将SQLite迁移到Postgres
