Ruby rails s error

當我嘗試運行rails s時，我收到了這個巨大的錯誤，我剛剛安裝了ruby以及PostgreSQL。感謝幫助。這也是我跑rails s後，我也做了一個類似的問題，如果在任何方式儘可能Rails Forem installation assistance我還是真的新的Ruby只是要記住。再次感謝。Ruby rails s error

檢查您的數據庫連接設置？ – wRAR 2013-02-15 01:18:15

psql（PostgreSQL）8.4.13 包含對命令行編輯的支持 – Frankrd3 2013-02-15 01:22:09

您是否爲您的pg db設置了密碼？ – 2013-02-15 01:36:39

這是導致你的PostgreSQL連接失敗。確保你的config/database.rb設置正確。

如果您認爲它接下來看看您的端口設置。「/tmp/.s.PGSQL.5432」？

這是一個套接字文件;它沒有任何內在錯誤。 – 2013-02-15 02:13:15

我意識到，但它也表明它的端口也是5432 – 2013-02-15 02:15:01

您的postgres服務正在運行？服務postgresql開始
