如何解決rake db：使用'rake-10.0.4'遷移

Question

tim@ubuntu:~/rails_projects/sample_app$ bundle exec rake db:migrate 
ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available in RDoc 2.4.2+) instead. 


tim@ubuntu:~/rails_projects/sample_app$ gem uninstall rake --version 10.0.4

我不想爲rake-10.0.4上的這些依賴性回滾到rake-0.8.7。

有沒有其他解決方案來解決這個問題？

如果您使用的是rake version> 10.0.0。請編輯您的Rakefile

來自：

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

到：

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