i’m reading _Agile Web Development with Rails (4th edition) P1.0_, and I had no problem until page 80, where running _rake db:migrate_ command, get following error :
ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available in RDoc 2.4.2+) instead.
(See full trace by running task with --trace)
I installed Rails 3.0.5 and Ruby 1.8.7, according to the instructions of the Book, and i work with Mac os X Lion 10.7.5.
Can someone help me with this problem?
Thanks so much
