ruby on rails - Trying to use rspec, but getting an error that rspec-core 2.2.1 has been activated, but my Gemfile requires rspec-core 2.1.0 -


i've update gems. i've created sample rails app , have following in gemfile:

source 'http://rubygems.org'  gem 'rails', '3.0.3' gem 'sqlite3-ruby', :require => 'sqlite3'  group :development   gem 'rspec-rails' end  group :test   gem 'rspec'   gem 'webrat', '0.7.1' end

however, when run 'rspec spec/', following message: /home/jeff/.rvm/gems/ruby-1.9.2-p0/gems/bundler-1.0.7/lib/bundler/runtime.rb:27:in `block in setup': have activated rspec-core 2.2.1, gemfile requires rspec-core 2.1.0. consider using bundle exec. (gem::loaderror)

try using bundle update rspec , bundle update rspec-rails. gemfile.lock file, located in root directory, specifying version number each gem.
