I'm trying to run a migration but I keep getting the error message that is:
rake aborted! Undefined method prerequisite for nil:NilClass.
It seems that somehow I activated a gem called rake 0.9.3.beta.1
- however I have since changed the gem bundle install
and run bundle show
rake and it shows that rake 0.9.2
is installed. I'm using Git for the first time so I thought that maybe it had something to do with the application still using the beta version of rake - but I've done a push and it shows that the gemfile has been updated.
and when I look down into the gem libraries I can only see the rake 0.9.2
version. Where should I be looking?
I also have a Rails:Railtie deprecated warning - but I'm thinking that this doesn't have anything to do with my migration problems. Its telling me to use config.app_generators in config/application.rb instead of Railtie - but i can't see that in the file.
This is the Config/application.rb file
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
Bundler.require *Rails.groups(:assets) if defined?(Bundler)
module CrowdshareApp
class Application < Rails::Application
config.encoding = "utf-8"
config.filter_parameters += [:password]
config.assets.enabled = true
end
end
My Gemfile looks like this:
source 'http://rubygems.org'
gem 'rails', '3.1.0.rc5'
gem 'sqlite3'
group :assets do
gem 'sass-rails', "~> 3.1.0.rc"
gem 'coffee-rails', "~> 3.1.0.rc"
gem 'uglifier'
end
gem 'jquery-rails'
group :development do
gem 'rspec-rails', '2.0.0.beta.18'
end
group :test do
gem 'rspec', '2.0.0.beta.18'
end
and the Gemfile.lock file has the following:
