錯誤的Heroku與運行耙分貝：遷移 - errno的:: ENOENT：沒有這樣的文件或目錄 - /app/db/schema.rb

Question

我試圖讓我的項目在Heroku上工作，但是當我試圖運行「耙DB：遷移」得到了以下

任何想法????

謝謝:)

PD：我覺得probles這裏

** Execute db:schema:dump 
rake aborted! 

因爲

數據寫入硬盤Rake任務，如耙分貝：模式：dump，與Heroku的臨時文件系統不兼容。

Answer 1

你沒有在你的應用程序中的DB/schema.rb文件？該文件應在應用程序名稱/ DB/schema.rb如果這是您第一次上傳的Heroku也許嘗試運行耙分貝：種子首先要創建架構文件，然後做你的遷移之後。

Answer 2

的問題是窗口...

的Windows重新命名/db文件夾/DB，和Heroku的突破如果發生這種情況。
