No sé cómo compilar la tarea 'db: migrar' con Rails 3.2.0.rc2

Question

Estoy intentando actualizar mi aplicación Rails a 3.2.0.rc2 pero cuando intento hacer un rake db:migrate --trace estoy ahora conseguir el siguiente mensaje de error:

DEPRECATION WARNING: The InstanceMethods module inside ActiveSupport::Concern will be no longer included automatically. Please define instance methods directly in ActionController::Base instead. (called from <top (required)> at /Users/Kyle/Desktop/skateparks-web/config/application.rb:4)

/Users/Kyle/.rvm/gems/ruby-1.9.2-p290@skateparks/bin/rake:19:in `<main>' 

la advertencia desaprobación parece estar en lo que respecta a esta línea en application.rb:

Bundler.require(:default, :assets, Rails.env) if defined?(Bundler) 

se supone que esto debe ser eliminado o cambiado en la última versión de Rails? Intenté eliminar esta línea y ejecutar Migrate nuevamente. Entonces ya no recibo la advertencia pero sigo recibiendo el error Don't know how to build task 'db:migrate'. ¿Algunas ideas?

Haciendo un bundle exec rake -T se obtiene la siguiente:

Parecería como si todos mis rake db tareas están desaparecidos.

Answer 1

Hay algo muy funky pasando con sus versiones de gemas. Si miras tu gemfile.lock está usando las versiones 3.2.rc2 de railties, activesupport y activemodel, pero las otras versiones están por todas partes (ar es 1.6, action mailer es 0.6.1, etc.).

no estoy seguro de cómo se metió en este estado, pero que iba a tratar ya sea bundle update o eliminar Gemfile.lock y ejecutando bundle install (en teoría esos 2 son equivalentes) y especificando la versión exacta de los carriles que desee (especialmente cuando busca una versión preliminar de los rieles.)

Answer 2

Desde el comando rake db:migrate --trace, las tareas de rake no se cargan. , y no podría obtener el esquema de ruta correcto. y ejecuta rake -T localmente lista db:migrate como una de las tareas de rake? Si no, sus rieles están mal configurados ... bueno, no trabajé con los rieles 3.2.0rc2, pero busqué en Google y encontré algunos enlaces. Por favor, consulte los enlaces inferiores a este le ayudaría ..
