Reverting to 0.8.7 resolves the issue. A stacktrace will be forthcoming.

Mike Jansen

I had a similar issue when running rake db:migrate on a new rails app. I reverted 0.8.7 to resolve. Stack trace:

Seeing the same issue with 0.9.0, which was upgraded as part of a move to Rails 3.0.7.

This is absolutely brand new rails app, made from the rails guides. It barely contains anything.

Error occurs when Gemfile.lock contains "rake (0.9.0)". Changing it to "rake (0.8.7)" stops this error.

Two issues here: (1) dimitko's issue is that the built in rake command is being mixed with the new gem's library files. Arranging your $PATH environment list so that the gem version of rake has precendence over the built-in version should fix that. If you are using bundler, you might also want to try 'bundle exec rake'.

The second issue (mjansen401 and r00k above) is that the new version of rake does not put its DSL commands (task, file, desc, import, etc) in the root of the Object namespace anymore (placing them in Object meant every object has a task command, not very nice . The DSL commands are available by mixing in the Rake::DSL module into any module needing the commands.

Until rails is updated to work with Rake 0.9.x, put the following in your project Rakefile before the call to Application.load_tasks:

class Rails::Application
  include Rake::DSL if defined?(Rake::DSL)
end

Let me know if these work for you.

dimitko

Thanks for your timely reply, Jim.

For me the "bundle exec rake" solution AND putting the code snippet in the Rakefile worked (none of them alone, only both together). I would avoid adjusting PATH or symlinking rake for the simple reason that when I deploy the application to a live server, I would have to repeat that for every new version of the gem from now on.

I am still far from a Rails guru and this advice really put me back on track. Thanks for the hint! <3

Sweet. Glad that worked for you.

Actually, you shouldn't have to change $PATH for each new gem. The 'gem' command installs executable stubs for all of its gems in a particular directory. You can find that directory with:

gem env | grep 'EXECUTABLE DIR'
  - EXECUTABLE DIRECTORY: /Users/jim/.rvm/gems/ruby-1.9.2-p136@090/bin

Mine is a directory setup by rvm, so it depends version of Ruby and the gemset, but if you are not using rvm it will be in a fixed directory. In any case, the directory doesn't depend on the version of the gem. Just make sure the gem executable path occurs before the built-in ruby directory in $PATH.

I have the same issue where task is undefined after upgrading to 0.9.0. I cannot find any rake 0.8.7 binaries on my machine:

blah@schmick:~/abitlucky/web/luckyonrails$ locate rake | grep bin | grep -v rake2thor
/usr/local/ruby/bin/rake
/usr/local/ruby/lib/ruby/gems/1.9.1/gems/rake-0.9.0/bin
/usr/local/ruby/lib/ruby/gems/1.9.1/gems/rake-0.9.0/bin/rake

/usr/local/ruby/bin/rake --version
rake, version 0.9.0

bundle exec rake doesn't help and just prints out the same error:

bundle exec rake
Loading data_fabric 1.3.1 with ActiveRecord 3.0.1
WARN: rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
rake aborted!
undefined method `task' for #

(See full trace by running task with --trace)

So adding the following to my Rakefile worked, even though I was not getting the 'uninitialized constant Rake::DSL' error.

  class Rails::Application
       include Rake::DSL if defined?(Rake::DSL)
  end

Include Rake::DSL if defined for Rake 0.9 compat #17
