Rake 0.8.7 and ActiveSupport 3.0.1

Question

Hello guys,

I am running Ruby 1.9.2. I have rake 0.8.7 installed. However running rake inside a Rails application gives me the following:

(in /usr/home/users/dimitar/Rails/spek)
Could not find activesupport-3.0.1 in any of the sources
Try running `bundle install`.

So I go ahead and run bundle install again and everything looks good:

Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.

But rake still gives me the same error message. Any suggestions?

Actually the problem seems to come from the config/boot.rb file:

# Set up gems listed in the Gemfile.                                                                                                                               
gemfile = File.expand_path('../../Gemfile', __FILE__)
begin
  ENV['BUNDLE_GEMFILE'] = gemfile
  require 'bundler'
  Bundler.setup
rescue Bundler::GemNotFound => e
  STDERR.puts e.message
  STDERR.puts "Try running `bundle install`."
  exit!
end if File.exist?(gemfile)

Do you have multiple Ruby interpreters installed (maybe via rvm or some other method)? If so, are you sure that the right one is active?

Things to look at:

which ruby
which rake
ruby -e 'puts $:' # To show the LOAD_PATH for gems
