耙db中的錯誤：遷移

我一直在嘗試從Rails 2.3升級到Rails 3我的應用程序。我得到了導軌s工作沒有錯誤，但沒有出現，因爲我沒有遷移數據庫。已經有無數的錯誤，我有固定試圖運行耙分貝：遷移，但我不能讓過去這...耙db中的錯誤：遷移

rake aborted! 
no such file to load -- config/environment 

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

我的配置環境是

#Load the rails application 
require File.expand_path('../application', __FILE__) 

# Initialize the rails application 
AppName::Application.initialize!

與跟蹤

有什麼建議嗎？

用'--trace'運行它並在這裏發佈結果可能會有所幫助。 – bricker

添加了跟蹤 –

'/ lib/tasks/account.rake'中有什麼？它看起來像*也許*你需要將該文件中對'environment.rb'的引用更改爲相對路徑（即'../../ config/environment.rb'。這只是一個猜測，所以我贏了不會將它作爲答案發布 – bricker

我不知道，如果你已經看到了這一點，但有一個Rails插件，提供耙任務，以幫助在這次升級中：https://github.com/rails/rails_upgrade

它給你：

rake rails:upgrade:check 
rake rails:upgrade:configuration

但我認爲什麼你需要做的就是生成一個新的空軌3應用程序，並將生成的config/environment文件複製到您的應用程序中。
