錯誤：將SQLite遷移到Postgres

我使用標準配置（SQLite 3）開發了我的應用程序。我想在heroku上部署，並且必須更改爲postgresql。錯誤：將SQLite遷移到Postgres

但是當我試圖遷移我的數據庫模式時遇到了這個錯誤。

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'

我不知道我現在要做什麼。我的寶石文件包括了「PG」和我的database.yml的樣子：

# 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:

運行PostgreSQL - 通過終端我可以訪問它。

編輯：我注意到，我在嘗試創建postgre數據庫時出現以下錯誤：

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'

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

其中之一，這兩個錯誤都是rails中的語法錯誤，並且與Postgres無關。關於第一個錯誤 - config/initializers/session_store.rb的第三行是什麼？至於第二個，看起來像輸出中只列出了核心文件 - 是否有更多的跟蹤或任何其他有關該錯誤的信息？ – 2013-02-14 20:24:23

session_store中的第3行是「BillsCmd :: Application.config.session_store：cookie_store，key：'_bills_cmd_session'」。是的，我認爲這只是製造麻煩的紅寶石。在1.9上更新ruby的最佳方式是什麼？使用rvm命令「rvm install current && rvm use current」？ – Adrian 2013-02-14 20:56:42

這並不容易......但我得到了Ruby 1.9.3的安裝。我現在手動創建了postgre，並通過輕敲進行遷移。但是當我嘗試運行這個RoR應用程序時，我收到了一條新的錯誤消息 - 我粘貼了[pastebin]（http://pastebin.com/QkiKcFS6）。我甚至在「軟件包安裝」和「軟件包更新」之後收到此消息 – Adrian 2013-02-14 21:33:10

搜索和測試不同的建議了幾個小時之後，我嘗試了那些在這裏：stackoverflow

特別是Darren的條目是我的解決方案。現在我的RoR App正在運行Postgre。
