ERROR: 'rake/rdoctask' is obsolete and no longer supported

Question

Out of the blue, I started getting the following error message:

(in /Users/me/.rvm/gems/ruby-1.9.3-p125@mysql2/gems/rails-0.9.5)
rake aborted!
ERROR: \'rake/         


        

Answer 1

Take a look at similar problem solution on StackOverflow

Another option is to use (example taken from Redmine Rakefile)

require 'rdoc'
require 'rdoc/task'

Instead of

require 'rake/testtask'
require 'rake/rdoctask'
