Problemas al ejecutar rake db:migrate

[Glendis Arias]

Hola

Estoy trabajando en un proyecto nuevo con Ruby on Rails. Aplique (rake db:setup) para iniciar mi aplicación (GenieACS) y me indica que tengo migraciones pendientes.

Database 'db/development.sqlite3' already exists

Database 'db/test.sqlite3' already exists

You have 6 pending migrations:

  20160202145722 CreateUsers

  20160211140635 CreatePermissions

  20160211142120 CreateRoles

  20160212123229 CreateUserRoles

  20160218145427 AddRoleIdToPermission

  20160219094206 RenamePermissionsToPrivileges

Run `rails db:migrate` to update your database then try again.

[root@genieacs-rhel genieacs-gui]# rails db:migrate

rails aborted!

 

He intentado realizar la migración ( rails db:migrate, rake db:migrate) pero ocurre el siguiente error: 

rake aborted!

NoMethodError: undefined method `Migration' for ActiveRecord:Module

Tasks: TOP => db:migrate

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

Revise los archivos de migración y no identifico cual es el problema. Estoy trabajando con (Ruby 2.3.1  y Rails 5.2.1). Este es uno de los archivos: 20160202145722_create_users.rb  donde modifique de forma manual la versión [5.2]

class CreateUsers < ActiveRecord::Migration [ 5.2 ]

  def change

    create_table :users do |t|

      t.string :username

      t.string :password

      t.timestamps

    end

  end

end

Lei en un foro los siguiente y lo intente ejecuta, pero sigo con el problema: 

# rake db: reset

# rm -f db/*.sqlite3

# rake db:create

# RAILS_ENV=development rake db:migrate

# rails s -e development

Por favor si me pueden ayudar, no se cual es el problema.....

Hola,

¿has probado a no dejar espacio entre ActiveRecord::Migration [ 5.2 ] ?

en vez de rake, probale con la palabra 'rails'

$ rails db:migrate

En caso de poder borrar la base de datos sin problemas, yo ejecutaría:

$ rails db:drop

$ rails db:create

$ rails db:migrate
