導軌 - 耙分貝：創建錯誤

Question

我試着運行耙分貝：創建一個MySQL數據庫，但得到的錯誤

$ rake db:create 
rake aborted! 
undefined method `task' for #<Sharebox::Application:0x0000010085a010> 

伊夫運行--trace並獲得信息

這是我的database.yml文件

development: 
    adapter: mysql 
    encoding: utf8 
    reconnect: false 
    database: sharebox_development 
    pool: 5 
    username: root 
    password: 
    host: localhost 

伊夫重新安裝紅寶石，導軌和MySQL，但仍然得到同樣的錯誤任何幫助，將不勝感激。歡呼聲

您應該在您的GemFile中精確定位您的Rake版本。

Rake 0.9剛剛出來，但打破了Rails。

這裏的dhh鳴叫：

Rake 0.9,released yesterday, broke Rails (and others). While we wait for a fix, you'll want gem 'rake', '0.8.7' in your Gemfile.

嘗試嗎？

編輯：另外，如果您真的需要Rake 0.9而不是Rake 0.8.7，請參閱that post。也許這種解決方案會爲你工作。
