Problemas con migraciones para iniciar Ruby on Rails

Rails
1

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.
rails db:migrate
rails aborted!

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

rake aborted!

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

Leí en un foro que podía resolver con lo siguiente, pero lo intente y sigue el mismo 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…

Al parecer el problema lo está causando el versionado que estás usando en la migración. Debes cambiar [5.2] por [5.0], quedaría algo así:

class CreateUsers < ActiveRecord::Migration [5.0]
  def change
    create_table :users do |t|
      t.string :username
      t.string :password

      t.timestamps
    end
  end
end
