ntão, eu tenho tentado fazer com que o redmine trabalhe seguindo todos os tipos de tutoriais na web, mas sempre fico preso na mesma etap

G:\Ruby187\apps\redmine>rake db:migrate
NOTE: SourceIndex.new(hash) is deprecated; From G:/Ruby187/apps/redmine/config/.
./vendor/rails/railties/lib/rails/vendor_gem_source_index.rb:100:in `new'.
rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
rake aborted!
uninitialized constant ActiveSupport::Dependencies::Mutex

(See full trace by running task with --trace)

Procurando o erro, eles me dizem para alterar a linha Rakefile:

require 'rake/rdoctask'

par

require 'rdoc/task'

Mas, então, recebo o erro:

G:\Ruby187\apps\redmine>rake db:migrate
NOTE: SourceIndex.new(hash) is deprecated; From G:/Ruby187/apps/redmine/config/.
./vendor/rails/railties/lib/rails/vendor_gem_source_index.rb:100:in `new'.
rake aborted!
no such file to load -- rdoc/task

(See full trace by running task with --trace)

Aqui estão algumas informações sobre minha configuração:
