Rake 0.9.1 导致 rake:db:migrate 产生弃用问题，无法降级到 0.8.7

Question

I ran a bundle install on my Gemfile recently, and tried to rake:db:migrate. This migration didn't work, and outputs:

WARNING: Global access to Rake DSL methods is deprecated.  Please include
    ...  Rake::DSL into classes and modules which use the Rake DSL methods.
WARNING: DSL method SampleApp::Application#task called at /Users/joshuaballoch/.rvm/gems/ruby-1.9.2-p180@rails3tutorial3/gems/railties-3.0.3/lib/rails/application.rb:214:in `initialize_tasks'

I read on another post that I should uninstall 0.9.1, but for some reason some gem I have requires 0.9.1 after the uninstall, so I don't know how to fix this. Any suggestions?

FYI my gemfile is:

source 'http://rubygems.org'

gem 'rails', '3.0.3'



gem 'sqlite3-ruby', '1.3.2', :require => 'sqlite3'
gem 'gravatar_image_tag', '1.0.0.pre2'
gem 'will_paginate', '3.0.pre2'



group :development do
    gem 'rspec-rails', '2.3.0'
    gem 'annotate-models', '1.0.4'
    gem 'faker', '0.3.1'
end

group :test do
    gem 'rspec', '2.3.0'
    gem 'webrat', '0.7.1'
    gem 'factory_girl_rails', '1.0'
end

Answer 1

Have you tried running it like so: bundle exec rake db:migrate

the bundle exec command runs your request in the environment defined by the bundle, so if your global gems differ this may help.

If not, you can add gem "rake", "0.8.7" to your gemfile, bundle install then try again. Your other dependency should still be met as you aren't removing 0.9.1, just asking bundle exec to use a different version.

Rails 3.0.8 was released yesterday, and includes "Fixing Rake 0.9.x integration" . Worth a try.
