我剛剛開始學習Rails。 當我嘗試「rake db:migrate」時,發生以下錯誤。rake db:遷移失敗
rake aborted! FATAL:對等身份驗證失敗,用戶「KT1」
似乎有一些錯誤的database.yml,但我不知道如何解決。 請給我一個建議。
非常感謝您的評論和編輯。我使用postgresql(0.13.2)。我的環境如下。 的Ubuntu 11.10 紅寶石1.8.7 的Rails 3.2.3 寶石21年8月1日
的database.yml如下。
# PostgreSQL. Versions 8.2 and up are supported.
#
# Install the pg driver:
# gem install pg
# On Mac OS X with macports:
# gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
# On Windows:
# gem install pg
# Choose the win32 build.
# Install PostgreSQL and put its /bin directory on your path.
#
# Configure Using Gemfile
# gem 'pg'

我在空白也試圖與用戶名。那麼錯誤來
rake aborted!
FATAL: role "kenji" does not exist
(賢治是我在Ubuntu的用戶名)。
你可以發佈你的'database.yml'嗎?阻止任何敏感數據。你試圖使用哪種數據庫類型(MySQL,PostgreSQL等)? – Alex 2012-04-01 11:57:47
