我正在使用gem版本2.0.7和rails版本3.0.7。如何解決rake db:在RoR中遷移錯誤?

雖然我運行rake db:migrate命令,但它拋出了以下錯誤。

$ rake db:migrate --trace

錯誤消息的關鍵部分是這樣的:

ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (ava 

如果您搜索的StackOverflow或谷歌的錯誤信息,你會發現在同一主題的至少有三個不同的問題,等等這樣的:

ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available in RDoc 2.4.2+) instead

在寫作時的最高投票答案建議從編輯的Rakefile:

require 'rake' 
require 'rake/testtask' 
require 'rake/rdoctask' 
require 'tasks/rails' 

到:

require 'rake' 
require 'rake/testtask' 
require 'rdoc/task' 
require 'tasks/rails' 

如果我是你,我會嘗試升級的Rails 3.2,看看問題是否仍然存在。如果這不是一個選項,那麼較老的問題將有望得到幫助。

我已經嘗試過改變,但它引發同一error.That。這就是爲什麼我張貼的問題 – selvam

對。爲了將來的參考,如果你在問題中告訴我們你已經嘗試了什麼,它會讓人們更容易幫助。 – lime

我改變了上面提到的rake文件。但這是行不通的。 – selvam

它可以通過安裝耙的舊版本,並卸載當前版本10.1.0來解決它:

gem install rake --version 0.8.7 
gem uninstall rake --version 10.1.0
