How to solve it.

The key part of the error message is this:

If you search for the error message on StackOverflow or Google you will find at least three different questions on the same topic, among others this:
ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available in RDoc 2.4.2+) instead
The highest voted answer at the time of writing suggests editing your Rakefile from:
require 'rake'
require 'rake/testtask'
require 'rake/rdoctask'
require 'tasks/rails'
to:
require 'rake'
require 'rake/testtask'
require 'rdoc/task'
require 'tasks/rails'
If I were you, I would try to upgrade Rails to 3.2 and see if the problem persists. If that is not an option the older questions will hopefully be of help.
it can be solved it by installing an older version of rake, and uninstalling current 10.1.0 version:
gem install rake --version 0.8.7
gem uninstall rake --version 10.1.0

$ rails -v
Rails 2.3.5
$ ruby -v
ruby 1.9.3p194 (2012-04-20) [i386-mingw32]
I had the same problem, but it was the result of having the gem rmagick.
I ran the following:
gem uninstall rmagick
gem cleanup
And then re-ran bundle in my stack and it worked for me again.
I have solved this issue. Use following command and problem gone
gem install rails
This will install updated rails and all thing working find again.
Running bundle exec rails s worked for me.
My project was using Rails 3.x but when I ran rails -v I got 2.3.17 which is the version used by a project I worked on just before. Somehow installing this version must have be set as "default".
Could someone explain this ?
if you are using latest version of rails 3 or rails 4 then use class_attributes instead of write_inheritable_attribute, i.e.
class_attribute :variable_name
self.variable_name = value
instead of
write_inheritable_attribute(:variable_name, value)
I had this issue, and it happens that I was in using the wrong ruby and gemset in rvm.
(#jeremy-f and #alex-villa are on the right track to identifying the problem itself.)
The problem here is that the rails ... command in Rails version 2 is a generator, equivalent to rails new ... in Rails 3+. So rails s is a Rails 2 command to generate a new Rails 2 app called "s" (whereas most of us when we write rails s intend the Rails 3 usage, i.e. start a server!)
If you install a gem, it will usually install its binary in the path, so you should be able to cause this error by doing gem install rails -v 2.3.15 then rails s as the OP says.
Three ways to fix it:
gem install rails to install a newer version of Rails (you may have to specify a version >= 3.0)
Run the app with bundle exec rails s (only if you have Rails 3 in your Gemfile)
The usual way to run a Rails 2 project is simply script/server
when I run any rails specific command in the console it gives me an error. For instance, i tried
rails -v then it gives me error
/usr/local/lib/ruby/1.9.1/x86_64-linux/rbconfig.rb:194:in `each': rehash occurred during iteration (RuntimeError)

The same happens for gem commands. Ruby is working fine.
Please Help. Thanks in Advance.
Not sure if that is the problem but according to the rails website, they only support ruby 1.8.7 or 1.9.2 .
and it seems you got 1.9.1.
The error message is showing that when you run rails, it is using 1.9.1. Per Wissam's comment, not sure if the ruby version is the problem, but you definitely need to make sure you are running on 1.9.2 before troubleshooting any further.
Did you install RVM? If so, have you set the default ruby? Try typing "rvm info" at the prompt. If you have RVM installed, it will print out a bunch of useful info about your ruby version. If you don't, it will say command not found. If you do have it, then you can select a different ruby version using "rvm use 1.9.2".
If you don't have RVM installed, then there are probably two versions manually installed on your host, and you'll need to figure out why rails is using 1.9.1.
In any case, I highly recommend using RVM. https://rvm.io.

I did: sudo gem uninstall rake -v 0.9 then added gem 'rake', '0.8.7' to my gem file.
Rather than downgraded your Rake, you can fix your application.rb file by adding the line:
include Rake::DSL
Just add that within the class Application and you should be good!
Example application.rb:
module AppName
class Application < Rails::Application
include Rake::DSL
end
end
gem 'rake', '0.8.7' in Gemfile works, if may also need to run bundle update rake if bundler complains about rake locked '0.9.0'.
Here is the issue on rake github page https://github.com/jimweirich/rake/issues/33
I am on jruby. Here are the exact commands that got me rid of the problem.
jruby -S gem uninstall rake
jruby -S gem install rake -v 0.8.7
edit Gemfile: Add this after gem 'rails':
gem 'rake', '0.8.7'
finally run:
jruby -S bundle update rake
Run these 2 lines at the command prompt. It will remove rake 0.9.0.
substitute your username where it shows "username"
GEM_HOME='/Users/username/.rvm/gems/ruby-1.9.2-p180#global' GEM_PATH='/Users/username/.rvm/gems/ruby-1.9.2-p180#global' gem uninstall rake
GEM_HOME='/Users/username/.rvm/gems/ruby-1.9.2-p180' GEM_PATH='/Users/username/.rvm/gems/ruby-1.9.2-p180' gem uninstall rake
Then install the correct gems:
rvm gem install mysql2 -v 0.2.7
rvm gem install rake -v 0.8.7
Update the MySQL gem (statment here show for x86_64 intel install):
env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
When you create a new app:
rails new -d mysql
you shouldn't need to change the gemfile or use bundle exec
I hope this makes sense. This post wont let me layout the syntax where it is readable.

Anyone experienced the same issue? What could possibly be wrong? Note that I am running Rails 3.0.3, you may also be interested in the content of my Gemfile:
source 'http://rubygems.org'
gem 'rails', '3.0.3'
gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'mysql2'
gem 'legacy_data'
gem 'resources_controller', :git => 'git://github.com/ianwhite/resources_controller'
gem 'will_paginate', '3.0.pre' # pagination
gem 'jquery-rails', '>= 0.2.6'
gem "rmagick" # sudo aptitude install libmagick9-dev
gem "paperclip", "~> 2.3"
gem "nested_form", :git => "git://github.com/madebydna/nested_form.git"
gem "meta_search"
gem "hirb"
gem "devise"
gem "rails_admin", :git => "git://github.com/sferik/rails_admin.git"
How can I fix this problem?
As explained in mordaroso's answer, there is a problem in Rake 0.9.0. You need to temporarily downgrade Rake in order to avoid it:
run: gem uninstall rake -v 0.9 (add sudo unless you use rvm)
add to your Gemfile: gem 'rake', '~> 0.8.7'
and then run: bundle update
You can skip the first step, but then you have to run rake using bundle exec, for example:
bundle exec rake db:migrate
Otherwise you get the following error.
rake aborted!
You have already activated rake 0.9.0, but your Gemfile requires rake 0.8.7. Consider using bundle exec.
Update
As Alex Chaffee noticed in a comment for Pablo Cantero's answer, that you might need to do the following to uninstall Rake if you still see the problem
rvm use #global && gem uninstall rake -v 0.9.0
rvm use # && gem uninstall rake -v 0.9.0
Also try the solution suggested in Duke's answer.
I had the same exception when running the 0.9.0.beta.4 version of Rake.
It looks like the new Rake::DSL is not loaded properly.
So I added following code to my Rakefile:
require 'rake'
# Rake Fix Code start
# NOTE: change 'Anelis' to your app's module name (see config/application.rb)
module ::Anelis
class Application
include Rake::DSL
end
end
module ::RakeFileUtils
extend Rake::FileUtilsExt
end
# Rake Fix Code end
MyApp::Application.load_tasks
That way I was able to run my Rake tasks again.
I know that this is not a elegant solution. But if you have to use the --pre version of Rake it might be all right to use this quick hack.
Note: This was just fixed in Rails 3.0.8
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 Ruby on Rails is updated to work with Rake 0.9.x, put the following in your project Rakefile after "require rake" and before the call to Application.load_tasks:
class Rails::Application
include Rake::DSL if defined?(Rake::DSL)
end
I've created an issue for rails_admin about this same error.
The answer:
This is a general Rails problem: http://twitter.com/dhh/status/71966528744071169
There should be a 3.0.8 release soon that fixes it. In the mean time, you can add the following line to your Gemfile:
gem 'rake', '~> 0.8.7'
It's a problem in Rake (0.9.0), it was announced by DHH on Twitter.
Rake 0.9, which was released yesterday, broke Rails (and others). While we wait for a fix, you'll want gem 'rake', '0.8.7' in your Gemfile.
This has been fixed in Ruby on Rails 3.0.8.rc1 which should be released in a few days time.
Rake 0.9.1 has just been released which reverses the change that caused this error but adds a deprecation warning: https://github.com/jimweirich/rake/commit/44aec3ceac085740bce0c385bccd65fc4d1d911c
I use rvm, but uninstalling doesn't help me. So I manually remove all 0.9 files from .rvm/gems/ruby#global directory and everything becomes as before!
without the need to uninstall Rake 0.9.x, add
gem 'rake', '~> 0.8.7'
to your Gemfile and just type
bundle exec rake -T
When I try to run some rspec test cases I'm getting this error
I'm using linux rails 3.0.0, ruby 1.9.2 (with RVM)
config/boot.rb:8: uninitialized constant Bundler (NameError)
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' ..
But when do a gem list , it shows both
builder (2.1.2)
bundler (1.0.10)
so what can be the problem?
Just update your bundler, in latest version such issue is resolved.
'gem install bundler'
and then 'bundler install'
If you find again error, then delete GEM.lock file, then run bundler install. It may resolve the issue.
