I manually deleted a migration file name 20171125081136-create-task.js.



After deleting the migration file, I ran this command 



db:migrate:undo:all


While running this command I'm getting an error in the terminal:
ERROR: Unable to find migration: 20171125081136-create-task.js.



Due to this error I'm stuck and not able to undo other migration files that exists.






sequelize.js sequelize-cli

          In your case, you must add the deleted migration file back in because Sequelize requires it to roll back your migrations. If you don't have it, you can add a blank migration file titled 20171125081136-create-task.js. The file must have a down function that returns a successful promise.



          'use strict';
          

          
module.exports = {
          
  up: function(queryInterface, Sequelize) {
          
    return Promise.resolve()
          
  },
          

          
  down: function(queryInterface) {
          
    return Promise.resolve()
          
  }
          
};


          Going forward, if you want to delete a migration:




          1. Undo the latest migration: node_modules/.bin/sequelize db:migrate:undo

          2. Delete the latest migration file
